Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control sequence editing device, a control sequence editing method, a control program and a recording medium for performing machine control and the like.

[0002]

2. Description of the Related Art An example of a conventional control sequence editing apparatus is described in Japanese Patent Application Laid-Open No. 5-53641. As shown in FIG. 58, this editing device includes a batch process control device 2600, a display 2601, and an operation unit 2602.
, Process control processing device 2603, and controller 2
605, a process input / output device 2604, and a plant database 2606.

The conventional control sequence editing apparatus operates as follows. At the time of executing the batch process, analog data 2610 from the process (for example, a value (0 to 4000, etc.) obtained by AD conversion of the analog signal of the ammeter, etc.) is processed by the process input / output device 2604 as an engineering value (0,
30 [A]). The analog data converted into the engineering value is stored in the plant database 2606 as process data, that is, tag data.

On the other hand, the controller 2605 collects tag data to be presented from the plant database 2606 in order to provide various kinds of information to the operator, and the display 26
01 is displayed.

The operator refers to the execution status of the process displayed as the tag data on the display 2601 and issues a constraint condition for executing the process through the operation unit 2602. That is, the operator uses the display 260
Check the execution status of process 2607 displayed in 1.
A determination is made and a corresponding operation is performed on the operation unit 2602. As a result, the operation signal 2608 is output from the operation unit 2602.
Is output to the controller 2605.

The controller 2605 operates the operation signal 260.
When 8 is input, the control command signal 2611 for executing the process 2607 corresponding to the operation signal 2608 is output to the process input / output device 2604. The process input / output device 2604 receives the control command signal 2611 and outputs a device control signal 2609 to the process 2607.

Further, the data stored in the plant database 2606 is output as an output value from the control processing unit 2603 to the process 2607 via the process input / output unit 2604 by the processing of the controller 2605.

In this way, the batch process is executed by sequentially starting, controlling, and stopping the equipment corresponding to each process.

The screen format in this conventional example is shown in FIGS. 59 and 60. The information displayed on the screen is composed of three types of information, that is, whole batch information, process information, and detailed information. Two examples of FIGS. 59 and 60 are shown as the arrangement of areas (or windows) for displaying each information.

In the example shown in FIG. 59, the screen is first moved to the left and right.
The screen is divided into three areas, and the left area is further divided into upper and lower parts to divide the entire screen into three parts. The three display areas 2700 and 270 thus obtained
Batch information, process information, and detailed information are assigned to 1 and 2702, respectively.

In the example shown in FIG. 60, the screen is first moved up and down.
The screen is divided into three areas, and the upper area is further divided into left and right parts to divide the entire screen into three parts. The three display areas 2703, 2704, 2 obtained in this way
Batch information, process information, and detailed information are assigned to 705.

Conventionally, either one of the area arrangements shown in FIG. 59 or 60 has been adopted according to the application.

The specific display contents of each area are as follows.

In the whole batch area 2700, 2703, each production process of products produced by batch control is displayed in a box of process unit. Each box has
While displaying the process name, the status of whether the batch processing of the process is executed or not executed is changed by changing the display attribute (color change, blinking, etc.) or execution start, execution, execution end, etc. Notify the operator by the message output. By referring to this information, the operator can grasp the general steps from the start of production of the product to the end of production, the production method and the outline of the execution state.

In the process areas 2701 and 2704, detailed information of the process represented by one box in the entire batch area is represented by sub-process boxes and connecting lines. In this area as well, as in the case of the entire batch information, the execution of the batch processing of the box and the non-execution status are performed by changing the display attribute and outputting the message so that the progress status of the sub process can be grasped.

The boxes used here are classified into several box types, including a unit sequence start box, a status judgment box, a setting output box,
It is composed of a timer box, an inquiry input box, a message output box, a jump box, a token delete box, a user built-in processing box, a normal MS return box, an abnormal processing WAIT box, an abnormal declaration box and the like.

The detail areas 2702 and 2705 are areas for displaying a detailed display in which the inside of the process area including one box being executed in the process area is enlarged. In this process area, the processing of each box such as the unit sequence activation box and the timer box described above is further displayed with a symbolized mark.

For example, in the processing of one box in the process area 2701, the sequence program corresponding to the box type is executed. In these processes, for the timer box, the set timer time and elapsed time are displayed at the same time. In addition, in the box of other processing,
From the detail area 2702, it is also possible to expand the screen to directly display the parameters (tag data used for processing, equipment data, etc.) of the relevant sequence program, and to change the parameters on this screen.

As described above, a plurality of information (entire batch, each process, details of execution status) of different layers are displayed on one screen, and information such as pre-execution, execution, execution completion, etc. is displayed according to the execution status. By changing the display attribute according to the type and the like, the operator is made to understand the current progress status in the production process. Further, by monitoring the process on the screen shown here and issuing an input instruction from the input device as necessary, the constraint condition and the control procedure can be changed on the same screen.

As shown in FIG. 61, the entire batch area 2
By changing the display attribute of the box for the process displayed in the process area 2801 within 800,
The relationship between both layers can be specified on the screen. Furthermore, by enclosing the portion in the process area 2801 corresponding to the display range in the detail area 2802 with a box with a broken line or a solid line, it is also possible to identify and display the correspondence relationship between the information in both areas. Then, as shown in FIG. 62, a message is output according to the execution state of the control sequence to clearly indicate the relationship in each layer.

Further, the operator can directly control the process on the same screen as the monitoring screen by operating the operation unit 2602 (see FIG. 58) while grasping the process status based on the process monitoring screen shown in FIG. . Further, the operator touches and selects the vicinity of the operation guide shown in FIG. 62 to directly call and control the tag or the like so that the state of the corresponding process can be changed. In this way, control can be performed on the same screen while monitoring the control procedure during process execution.

FIG. 63 is a diagram for explaining the display when the information in each area cannot be stored in one area on one screen.
4 is an actual display example corresponding to FIG.

In FIG. 63, the entire batch information is in the area 300.
It is shown that the process information does not fit in 0 and the process information does not fit in the area 3001. Even in such a case, it is necessary to operate without operating the operator's screen by automatically determining the box states during batch process execution and automatically updating the displayed contents as shown in Fig. 64. The latest information on the latest process was provided.

[0024]

However, in the above-mentioned prior art, the first problem is that since the hierarchical structure is divided into only two layers, that is, the entire batch and the process, the batch processing as a rough processing is performed as a whole batch. When displayed in the area,
All the detailed processing must be displayed in the process area, and if the detailed processing contents are complicated, many blocks will be placed in the process area, making it difficult for the operator to grasp the flow of processing. It will be.

Next, the operation of the control sequence editing apparatus having the above configuration will be described in detail.

The editing program of the present invention executed by the computer 100 first creates the functional block 120 on the main storage device 103 as the highest functional block. The function block 120 displays the display screen allocated by the operating system 101.
20 is stored in the display screen storage variable data 121d, and the functional blocks under the functional block 120 are stored in the display screen of the display screen storage variable data 121d.
It is displayed by the lower functional block drawing processing 122a of 22. At this point in time, the functional block 120 has no subordinate functional blocks, so the display screen shows
No functional block is displayed.

When the operator uses the input device 105 to add a functional block under the functional block 120, the functional block addition processing unit 123b of the editing processing unit 123 of the functional block 120 newly adds the functional block to the main storage device 103. The function block 130 is generated. Then, the main storage device 1 of the functional block 130 is added to the array data 121b of the lower functional block address storage variable of the functional block 120.
The address on 03 is stored. Further, the generated upper functional block address storage variable data 121c of the functional block 130 includes the main storage device 1 of the functional block 120.
The address on 03 is stored. The generated functional block stores the display screen allocated by the operating system 101 in the display screen storage variable data 121d of its own functional block.

The function block stored in the array data 121b of the lower function block address storage variables of the function block 120 is the display screen storage variable data 121 of the function block 120.
It is displayed on the display screen stored in d. Similarly, when the functional blocks 131-133 are added under the functional block 120, the display screen of the functional block 120 shows
A plurality of functional blocks 130-133 are displayed. The functional blocks related to the subordinates of the functional block 120 are the function block automatic association processing unit 123f of the edit processing unit 123 of the functional block 120 and the functional block manual association processing unit 123g of the block processing unit 122 of the functional block 120. A connection relation is associated using the block addition process 122b and the connection destination functional block addition process.

Then, the connection line is drawn on the edit screen stored in the display screen storage variable data 121d of the function block 120 by the function block connection line drawing process of the edit processing unit 123 of the function block 120.

When the operator displays the display screen of an arbitrary functional block among the functional blocks under the functional block 120, the screen is displayed in the same manner as the functional block 120. Then, similar to the functional block 120, a functional block can be added under it.

In this way, the functional blocks manage the functional blocks as a hierarchical structure by associating the functional blocks under the functional blocks, and display the connection relation of the functional blocks under the functional blocks.

FIG. 6 is an explanatory diagram of a correspondence relationship between control sequence creation and functional blocks in machine control. When considering the creation of a control sequence in machine control, it is as follows.

The machine control device 200 includes a plurality of mechanical units 201.
In most cases, including -210, each mechanism operates independently. In addition, one certain mechanical unit 21
When attention is paid to 0, as shown by related operations 211 to 214, there are a plurality of series of operations that are sequentially operated.

When attention is paid to a certain related operation 211, there are a plurality of actuators for operating the actual mechanism, as indicated by actuators 215 to 217. There may be a related operation in one related operation.

Therefore, in the present embodiment, the structure for creating the control sequence is as follows.

The independent operations of the mechanical units 201 to 210 are referred to as control tasks 221 to 230, respectively. In addition, a series of operations of the machine control device 200 having a plurality of mechanical units 201 to 210 includes control tasks 221 to 23.
It includes 0 and is called a control task group 220. Further, a series of operations 211 to 214 in one certain mechanical unit 210 are block sequences 231 to
234. Furthermore, the actuator 2 in a series of operations 211, for example a series of operations 211.
Actuator operations 235 to 23 for operations 15 to 217
Let's call it 7.

Next, in consideration of the respective relationships in the control sequence creation configuration, the overall configuration of the functional block has a hierarchical structure as shown in FIG.

Under the control task group 300, control tasks 310 to 312 belong. Further, for example, under the control task 310, the block sequences 330 to 3 are
32 or actuator operations 323-325 belong. Further, for example, the block 340 belongs to the block sequence 330 as a block sequence or an actuator operation. In this way, the control task group 300 is placed at the top, and a hierarchical structure of control task → block sequence → actuator operation → block is formed.

In this embodiment, in order to realize the above-mentioned hierarchical structure, a functional block capable of expressing a control task group, a control task, a block sequence, and an actuator as a common block is prepared.

Block data part 1 of the functional block of FIG.
21 stores data relating to the functional block. The block function type storage variable data 121f stores any one of a control task group, a control task, a block sequence, and an actuator operation as the type of function block.

Further, each functional block has a hierarchical structure, and in order to associate the functional blocks thereunder, the block data portion 121 of the functional block of FIG. 3 is provided with lower functional block address storage variable array data 121b. The lower-level functional block address storage variable array data 121b not only stores the subordinate functional blocks, but also has a two-dimensional array structure so as to correspond to a grid, which is a plurality of display areas two-dimensionally arrayed on the edit screen. .

FIG. 8 shows the correspondence between the edit screen and the functional blocks subordinate to the functional block. The theoretical edit screen 400 is
The grid where the functional block is displayed on the edit screen is shown. The reason for "theoretical" is that not all the edit screens are displayed due to the restriction of the display area when actually displayed on the display device 104 of FIG.

Grid [0,0], grid [1,0] ... In theoretical edit screen 400, array data [0,0] and array data [1 corresponding to array 410 of function block address storage variables. , 0] are in a one-to-one correspondence, and it is possible to know in which display grid on the edit screen each functional block is displayed by the array configuration 410 of the functional block address storage variables (functional block address storage variable array configuration 410). = Array data 121b of the lower functional block address storage variable in FIG.

Next, the overall operation of this embodiment will be described in detail with reference to FIGS.

FIG. 9 is a schematic processing flowchart when the editing program is started. First, when the editing program is started by the computer 100, the computer 100
The MPU (not shown) generates one functional block on the main storage device 103 based on the editing program (step S1). At this time, in the block function type storage variable data 121g of the generated function block 500, the type =
The “control task group” is stored. The display screen storage variable data 121d includes the operating system 10
The display screen data assigned by 1 is stored.

Next, the MPU displays the edit screen on the display screen of the display device 104 based on the edit program 101 (step S2).

Next, the display processing of the edit screen will be described. The edit screen is provided corresponding to each functional block except the functional block corresponding to the actuator operation. The lower functional block drawing processing unit 122a draws a lower functional block under the control of the functional block. In parallel with this, the connection line between the subordinate functional blocks is drawn by the functional block connection line drawing processing unit 123a. The edit screen to be drawn is a display screen corresponding to the display screen storage variable data 121d.

FIG. 10 is a processing flowchart when the edit screen is displayed. First, M (not shown) of the computer 100
The PU is a lower layer (hereinafter referred to as "subordinate") of the functional block to be displayed on the editing screen, based on the editing program.
Whether or not there is a functional block is determined by referring to the lower functional block address storage variable array data 121b (step S10).

Subsequently, the MPU determines whether or not there is a subordinate functional block by referring to the array configuration 410 of the functional block address storage variables shown in FIG. Specifically, the array data [0,
0] is sequentially checked, and all of the array data [0, 0] to array data [X, Y] are checked. If it is determined that there is a subordinate functional block based on the array to be confirmed, the address of the information regarding the functional block is stored in the main storage device 103 in the array data, so the information regarding that functional block is stored. Is acquired (step S11).

Next, the functional block is displayed on the edit screen based on the acquired information about the functional block (step S12). At this time, the name storage variable data 121a
The function block name is read from, the icon for each type is read from the block function type storage variable data 121g, and displayed on the edit screen.

Next, it is confirmed whether or not all the subordinate functional blocks belonging to the functional block have been displayed (step S13). In the determination in step S13, if all the subordinate functional blocks have not been confirmed (step S13; No), the next functional block in the functional block address storage variable array data 121b is confirmed.

Then, again, one existing functional block is obtained based on the lower functional block address storage variable array data 121b (step S14).

Further, the connection source function block address storage variable array data 121h and the connection destination function block address storage variable array data 121i of the acquired function block are acquired.
It is determined whether or not there is a functional block having a connection relationship based on (step S15).

In the determination of step S15, if a functional block exists at the connection source or the connection destination (step S15; Yes), a connection line indicating the control flow between the functional blocks is displayed (step S16). At this time,
The acquired subordinate functional block is passed to the inter-functional block connecting line display process (see FIG. 11) described later as a functional block B10 for displaying a connecting line.

Next, it is judged whether or not the connection lines between all the subordinate function blocks are displayed (step S1).
7). If it is determined in step S17 that the display has not been completed for all the function blocks under the control (step S17; No), steps S14-step are performed for the next function block in the array data 121b of the function block address storage variables. The process of S16 is performed.

Next, the connection line display process (step S16) between the subordinate functional blocks will be described with reference to FIG.

First, in the edit screen display processing, the function block B11 that is the connection source is acquired from the array data 121h of the connection source function block address storage variable of the function block B10 that displays the connection line (step S2).
1). Next, the array data 121 of the connection destination function block address storage variable of the function block B10 for displaying the connection line.
The functional block B12 that is the connection destination is acquired from i (step S22). Next, the connection source function block B1
The number of acquisitions of 1 is determined (step S23).

In the determination of step S23, if the connection source functional block B11 does not exist (step S2
3; No), connection line display processing with the connection source functional block B11 is not performed.

In the determination in step S23, if the connection source functional block exists (step S23; Ye
s), comparing the function block display grid storage variable data 121j of the connection source function block with the function block display grid storage variable data 121j corresponding to the function block B10 displaying the connection line, and the connection source function block displays the connection line. It is determined whether the function block B10 to be displayed is on the upper side or the left side (step S24).

In the determination in step S24, if the connection source function block is not above or to the left of the function block B10 displaying the connection line (step S24; N
o), connection line display processing is not performed.

In the determination in step S24, if the connection source function block is above or to the left of the function block B10 displaying the connection line (step S24; Ye
s), the connection line is displayed (step S25). At this time, the function block B10 for displaying the connection line and the connection source function block B11 are passed to the connection line display processing shown in FIG.

Next, the number of acquired connection destination functional blocks B12 is determined (step S26).

In the determination in step S26, if the connection destination functional block B12 does not exist (step S2
6; No), the processing is terminated without performing the connection line display processing with the connection destination functional block.

If it is determined in step S26 that there is a connection destination function block, the function block display grid storage variable data 121j of the connection destination function block and the function block display grid storage corresponding to the function block B10 that displays the connection line are stored. By comparing with the variable data 121j, it is determined whether the connection destination function block B12 is on the upper side or the left side of the function block B10 displaying the connection line (step S27).

In the determination in step S27, the connection destination function block B12 displays the connection line in the function block B1.
If it does not exist above or to the left of 0 (step S
27; No), the processing is terminated without performing the connection line display processing.

In the determination in step S27, the connection destination function block B12 displays the connection line in the function block B1.
If it is above or to the left of 0 (step S27;
Yes), and the connection line is displayed (step S28). That is, the functional block B10 that displays the connection line and the functional block B12 that is the connection destination are passed to the connection line display processing (see FIG. 12).

Next, the connection line display processing will be described with reference to FIG. FIG. 12 is a processing flowchart of the connection line display processing.

First, the MPU (not shown) has a function block B10 and a connection source function block B1 for displaying the connection lines passed from the sub-functional block connection line display processing (FIG. 7).
1 or connection line drawing route data with the connection destination functional block B12 is acquired (step S31).

Next, it is determined whether or not the acquired connection line drawing route data is within the visible display area on the screen stored in the display screen storage variable data 121d in the functional block B10 for displaying the connection line. Yes (Step S
32). The method of obtaining the connection line drawing route data and the visible display area will be described later.

In the determination in step S32, if even one of the acquired connection line drawing route data is not within the visible display area (step S32; No), the connection line drawing route data is corrected (step S32). S33), the process proceeds to step S34.

On the other hand, when it is determined in step S32 that all of the acquired connection line drawing route data are within the visible display area (step S32; Ye
s), based on the connection line drawing route data, the connection line is drawn on the screen stored in the display screen storage variable data 121d corresponding to the functional block B10 for displaying the connection line (step S34).

Next, the visible display area of the edit screen and the display rule of the connecting line will be described. First, the visible display area of the edit screen will be described with reference to FIG.

The array data 121b of the lower functional block address storage variable of one functional block has a two-dimensional structure like the subordinate functional block array 900 of the functional block. However, since there is a limit to the range that can be displayed on the display device 104, it is not possible to display all functional blocks at the same time. Display area 90 on the screen
When 2 is a displayable range, the rest is a non-display area 901.

Therefore, although the functional block symbols 911 to 916 corresponding to the functional blocks are displayed on the screen, the functional block symbols 910 and 917 to 919 are displayed.
Is not displayed on the screen. However, it is necessary to display the connecting line even when the functional blocks on one side, such as the functional block symbol 915 and the functional block symbol 917, are in the non-display area. Further, since the display processing of the connecting lines in the non-display area 901 wastes processing time, it is necessary to prohibit the display processing of the connecting lines.

Next, the display rule of the connecting line indicating the direction of control flow will be described with reference to FIGS. 14 to 35. In the following description, the connection line is a line with an arrow pointing to the connection destination, and the transition direction of the control procedure follows the direction of the arrow. If the connection destination is below the same row of the display grid, a downward arrow line is displayed. Further, when the connection destination is the same right side of the display grid, a rightward arrow line is displayed. Furthermore, when the connection destination is the left side of the same side of the display grid, a left arrow line is displayed. Further, when the connection destination is above the display grid, a downward arrow line is displayed from above the connection destination so as to detour from the left side of the connection source.

Specifically, the horizontal transition on the display screen of the control procedure is as shown in pattern 1 (see FIG. 16) and pattern 2 (see FIG. 18). In addition, the transition from top to bottom on the display screen of the control procedure is the pattern 3
(See FIG. 20), pattern 4 (see FIG. 22) and pattern 5 (see FIG. 24). Furthermore, the transition from the bottom to the top on the display screen of the control procedure is the pattern 6 (see FIG. 26), the pattern 7 (see FIG. 28) and the pattern 8
(See FIG. 30).

Next, these connection patterns 1 to 8 will be described in detail.

The functional blocks displayed in the display area of one functional block are displayed in a size slightly smaller than the display area. As shown in FIG. 14, the coordinates of the position on the functional block for displaying the connection line are the display area left XoL, the display area right XoR, the display area upper YoT, the display area lower YoB, the functional block left XiL, and the functional block.

The connection line drawing route data of the patterns 1 to 8 is just the non-display area 901.
Therefore, when actually displayed on the display screen, it is necessary to display only the connection lines included in the visible display area 902 on the screen.

Therefore, the correction of the connection line drawing route data will be described with reference to FIGS.

First, as shown in FIG. 32, when the two functional blocks 1202 and 1203 to be connected to each other are within the visible display area 1201 (corresponding to the visible display area 900 in FIG. 13) on the screen, the connection is made. Since the line is also in the visible display area 1201, it is not necessary to correct the connection line drawing route data.

Next, as shown in FIG. 33, one of the two functional blocks 1212 and 1213 connecting the connecting lines is within the invisible display area 1210 (corresponding to the invisible display area 901 in FIG. 13). If it exists, it is necessary to correct the connection line drawing route data.

That is, in the case of FIG. 33, since the functional block 1212 exists in the invisible display area 1210,
Coordinates (XiR1, YiU) in the connection line drawing route data
The data from 1) to the coordinates (XiC2, YiU1) is converted from the connection line correction coordinates (XL, YiU1) to the coordinates (XiC2,
Change by YiU1). Here, XL of the connection line correction coordinates represents the position on the left side in the visible display area 1211 on the screen.

Further, as shown in FIG. 34, both of the two functional blocks 1222 and 1223 connecting the connecting lines are invisible to each other in the invisible display area 1220 (invisible display area 90 in FIG. 13).
(Corresponding to 1) and the connecting line exists in the visible display area 1221 (corresponding to the visible display area 902 in FIG. 13) on the screen, it is necessary to correct the connecting line drawing route data.

That is, in the case of FIG. 34, the functional blocks 1222 and 1223 are both invisible display areas 122.
Since it exists in 0, the coordinates (XiR1, YiU1) to the coordinates (XiC2, YiU) in the connection line drawing route data are displayed.
The data up to 1) is converted to connecting line correction coordinates (XL, YiU1)
To coordinates (XiC2, YiU1). Furthermore, from the coordinates (XiC2, YiU1) to the coordinates (XiC2,
YiT2) data up to coordinates (XiC2, YiU1)
To the connection line correction coordinates (XiC2, YB). Here, XL of the connection line correction coordinate represents a left side position in the visible display area 1221 on the screen, and YB represents a lower side position in the visible display area 1221 on the screen.

Next, as shown in FIG. 35, both of the two functional blocks 1232 and 1233 connecting the connecting lines are invisible display area 1230 (invisible display area 90 in FIG. 13).
(Corresponding to 1) and the connecting line is not inside the visible display area 1231 (corresponding to the visible display area 902 in FIG. 13) on the screen, it is necessary to correct the connecting line drawing route data. That is, in the case of FIG. 35, since the connecting line is not displayed, all the connecting line drawing route data is corrected to have no data.

In this way, the connection line drawing route data between the two functional blocks is corrected.

Next, the edit processing of the control sequence will be described.

The control sequence editing processing for handling the functional blocks includes control task addition processing, block sequence addition processing, and actuator operation addition processing (above,
37), display position movement processing of the subordinate functional blocks (see FIG. 38), deletion processing of the subordinate functional blocks (see FIG. 3).

Connection / disconnection between subordinate functional blocks (see Fig. 41)
There is.

The instruction of the editing process is given by the operator operating the input device 105 such as a keyboard or a mouse. First, the MPU determines whether or not the addition of the control task has been instructed (step S41). In the determination in step S41, when the addition of the control task is instructed (step S41; Yes), the process proceeds to the process of adding the functional block as the control task (step S42). In this case, the display position where the functional block is arranged and the type of the functional block (control task) are passed to the functional block addition processing shown in FIG. 14 (step S43). This functional block addition processing is performed by the functional block addition processing unit 123b (see FIG. 5) of the functional block that is being edited.

If it is determined in step S41 that the addition of the control task has not been instructed (step S41).
41; No), the MPU determines whether or not the addition of the block sequence is instructed (step S44).

When an instruction to add a block sequence is given (step S44; Yes), the process proceeds to the process of adding a functional block as a block sequence (step S45). In this case, the display position where the functional block is arranged and the type (block sequence) of the functional block are passed to the functional block addition processing shown in FIG. 14 (step S46). This functional block addition processing is performed by the functional block addition processing unit 123b of the functional block that is being edited.

When it is determined in step S44 that the addition of the block sequence is not instructed (step S44; No), the MPU determines whether or not the addition of the actuator operation is instructed (step S4).
7).

If it is instructed to add the actuator operation in the determination in step S47 (step S4
7; Yes), and the process proceeds to the process of adding a functional block as an actuator operation (step S48). In this case, the display position where the functional block is arranged and the type of the functional block (actuator operation) are passed to the functional block addition processing shown in FIG. 14 (step S49). This functional block addition processing is performed by the functional block addition processing unit 123b of the functional block that is being edited.

Here, the function block addition processing will be described with reference to FIG. When the type of the functional block is passed from the process (see FIG. 36) at the time of editing the control sequence (step S43), the functional block is added based on the type of the functional block.

First, it is determined whether or not the function block adding process is a control task adding process (step S7).
1).

When the functional block to be added is the control task in the determination of step S71 (step S71; Yes), a new functional block is generated and the block function type storage variable data 121g of the generated functional block is generated. The type as the control task is stored in (see FIG. 3) (step S72).

Next, in step S43, the process of editing the control sequence is performed on the variable block display grid storage variable data 121j of the newly generated functional block (see FIG. 3).
The display position passed from (see 6) is stored. The display screen storage variable data 121d stores the display screen assigned by the operating system 101. Further, upper functional block address storage variable data 121c
Is the main storage device 10 of the functional block that is being edited.
The address above 3 is stored, and a unique numerical value in all functional blocks is stored in the functional block number storage variable data.
Further, the address of the newly created functional block in the main storage device 103 is added to the array data 121b of the lower functional block address storage variable of the functional block being edited (step S77).

Next, automatic functional block associating processing is performed (step S78). The function block automatic association processing is performed by the function block automatic association processing unit 123f of the function block being edited. still,
The process of automatically associating functional blocks will be described later.

Next, the edit screen display process is performed, the screen is redisplayed, and the function block addition process ends (step S79).

If it is determined in step S71 that the function block addition processing is not the control task addition processing (step S71; No), it is determined whether the function block addition processing is the block sequence addition processing. Yes (step S73).

When the functional block to be added is a block sequence in the determination of step S73 (step S73; Yes), a new functional block is newly generated and the block function type storage variable data 121g of the generated functional block is generated. The type as a block sequence is stored in (step S74).

Next, the display position passed from the process (FIG. 13) at the time of editing the control sequence in step S43 (see FIG. 36) is stored in the functional block display grid storage variable data 121j of the newly generated functional block. .
The display screen storage variable data 121d stores the display screen assigned by the operating system 101.

Further, the upper functional block address storage variable data 121c stores the address of the functional block being edited on the main storage device 103, and the functional block number storage variable data stores a unique numerical value in all functional blocks. To do. Also, the array data 1 of the lower functional block address storage variable of the functional block that is being edited.
21b main memory 10 of the newly created functional block
The address above 3 is added (step S77).

Next, automatic functional block associating processing is performed (step S78). The function block automatic association processing is performed by the function block automatic association processing unit 123f, which will be described later, of the function block that is being edited. Next, the edit screen display process is performed, the screen is redisplayed, and the functional block addition process ends (step S7).
9).

When the functional block to be added is not the block sequence in the determination of step S73 (step S73; No), it is determined whether or not the functional block addition processing is the actuator operation addition processing (step S73). S75).

When the functional block to be added is the actuator operation in the determination of step S75 (step S75; Yes), a new functional block is newly generated and the block function type storage variable data 121g of the generated functional block is added. The type of actuator operation is stored (step S76).

Next, the functional block display grid storage variable data 121j of the above-mentioned newly generated functional block.
In step S43 (see FIG. 36), the display position passed from the process at the time of editing the control sequence is stored. The display screen storage variable data 121d stores the display screen assigned by the operating system 101.

Further, the upper functional block address storage variable data 121c stores the address of the functional block being edited on the main memory 103, and the functional block number storage variable data stores a unique numerical value in all functional blocks. To do. Also, the array data 1 of the lower functional block address storage variable of the functional block that is being edited.
21b) main memory 1 of the newly created functional block
The address on 03 is added (step S77).

Next, automatic association processing of functional blocks is performed (step S78). The function block automatic association processing is performed by the function block automatic association processing unit 123f, which will be described later, of the function block that is being edited. Next, the edit screen display process is performed, the screen is redisplayed, the screen is redisplayed, and the function block addition process ends (step S79).

If it is determined in step S47 that addition of the actuator operation has not been instructed (step S47; No), the MPU determines whether or not movement of the subordinate functional block has been instructed ( Step S5
0).

If it is instructed to move the subordinate functional blocks in the determination in step S50 (step S5)
0; Yes), and the process moves to the function block moving process (step S51). In this case, the moving position and the one or more functional blocks selected to be moved are passed to the moving process of the functional block shown in FIG. 15 (step S52). The movement processing of this functional block is performed by the functional block movement processing unit 123 of the functional block being edited.
d.

Now, the process of moving the functional blocks will be described with reference to FIG.

When the movement position and one or more functional blocks selected for movement are passed from the control sequence editing process (see FIG. 36) (step S52),
The movement position is stored in the function block display position storage variable data 121j of the selected function block (step S81). Next, the edit screen display process is performed, the screen is displayed again, and the functional block movement process ends (step S82). As a result, since the display position of the functional block is changed when the screen is displayed again, the moved functional block is displayed at the moved position.

If it is determined in step S50 that the subordinate functional block is not moved (step S50;
No), it is determined whether or not an instruction to delete the subordinate functional blocks has been given (step S53).

When it is determined in step S53 that the subordinate functional block is to be deleted (step S5)
3; Yes), and shifts to the function block deletion process (step S54). In this case, one or more functional blocks to be deleted are the functional block deletion processing (see FIG. 39).
Reference). This functional block deletion processing is performed by the functional block deletion processing unit 123e of the functional block that is being edited.

Now, the process of moving the functional blocks will be described with reference to FIG.

First, the control sequence editing process (FIG. 36)
When the functional block selected from is passed (step S
55), based on the lower functional block address storage variable array data 121b of the selected functional block, it is determined whether or not a lower functional block exists (step S91).

If it is determined in step S91 that there is a lower functional block (step S91;
Yes), and deletes all lower functional blocks (step S92). In this case, all the lower functional blocks to be deleted are passed to the functional block deletion processing (see FIG. 39) (step S93). Then, the processing of deleting the lower-level functional block is performed by the functional block deletion processing unit 123e of the lower-level functional block.

Next, if there is a functional block to which the functional block to be deleted is connected, the connecting line will not be displayed correctly. Therefore, the array data 121h of the connection source functional block address storage variable of the functional block selected in step S54. Then, it is determined whether or not the connection source functional block exists (step S94).

If it is determined in step S94 that there is a connection source functional block (step S9).
4; Yes), the address of the function block to be deleted is deleted from the array data 121i of the connection destination function block address storage variable of the connection source function block (step S9).
5), the process proceeds to step S96.

If it is determined in step S94 that there is no connection source functional block (step S9).
4; No), if there is a function block whose connection source is the function block to be deleted, in order to prevent the connection line from being displayed incorrectly, the connection destination function block address storage variable of the function block selected in step S55 is stored. It is determined from the array data 121i whether or not the connection source functional block exists (step S96).

If it is determined in step S96 that there is a connection destination functional block (step S9
6; Yes), the address of the function block to be deleted is deleted from the array data 121h of the connection source function block address storage variable of the connection destination function block (step S9).
7).

Next, the upper functional block address storage variable data 12 of the functional block selected in step S55.
1c deletes the selected function block from the array data 121b of the lower function block address storage variable of the upper function block indicated by 1c, and further deletes the selected function block from the main storage device 103 (step S98). ).

Next, the edit screen display process is performed, and the screen is displayed again (step S99). As a result, when the screen is displayed again, the selected functional block and its association are also deleted, so that the functional block and the corresponding connection line are not displayed either.

If it is determined in step S53 that the subordinate functional block is not deleted (step S53;
No), it is determined whether or not an instruction to copy a subordinate functional block has been given (step S56).

If it is instructed to copy the subordinate functional blocks in the determination in step S56 (step S5).
6; Yes), and shifts to the copy processing of the functional block (step S56). At this time, the copy position and one or a plurality of functional blocks to be copied are passed to the copy processing of the functional block shown in FIG. 17 (step S58). The copy processing of this functional block is performed by the functional block copy processing unit 123c of the functional block that is being edited.

Here, the copy processing of the functional block will be described with reference to FIG. First, it is determined whether or not there is a lower functional block based on the array data 121b of the lower functional block address storage variable of the copy source functional block passed from the control sequence editing process in step S58 (step S101).

If it is determined in step S101 that there is a lower functional block (step S101).
101; Yes), copy processing of all the lower functional blocks is performed (step S102). At this time, all the lower functional blocks to be copied are passed to the functional block copying process (step S103). The copy processing of the functional block at this time is performed by the functional block deletion processing unit 123e of the functional block being edited (regression processing). However, the copy position is the same as the display position of the copy source (the display position changes only in the functional block to be copied on the edit screen).

Next, new functional blocks having the same number of copy source functional blocks are newly generated, and upper functional block address storage variable data 1 of the newly generated functional block.
21c stores the address on the main storage device 103 of the functional block being edited, and stores the address of the newly created functional block in the array data 121b of the lower functional block address storage variable of the functional block being edited. An address on the storage device 103 is added (step S10).
4).

Next, the newly stored functional block name storage variable data 121a and the comment storage variable data 12
1f, actuator and control command setting data section 12
The setting value of the copy source functional block is copied to 1k (step S105). Then, the copy position passed in the process of step S58 is stored in the functional block display grid storage variable data 121j of the newly generated functional block (step S106).

Next, it is judged whether or not the copy source functional block has a connection relation based on the array data 121h of the connection source functional block address storage variable and the array data 121i of the connection destination functional block address storage variable ( Step S107).

If it is determined in step S107 that there is a connection relationship (step S107; Y
es), the corresponding functional block is acquired based on the array data 121h of the connection source functional block address storage variable of the copy source functional block and the array data 121i of the connection destination functional block address storage variable. Then, from the relative positions of the acquired functional block display grid storage variable data 121j of the functional block and the functional block display grid storage variable data 121j of the copy source functional block passed in the processing of step S58, The connection relationship is acquired, and the connection relationship is set by the connection source function block addition processing 122b and the connection destination function block addition processing 122c of the function block being edited (step S108).

Next, the edit screen is displayed and the screen is displayed again (step S109). As a result, the copied functional block is displayed when the screen is displayed again. Further, the same functional block as the copy source exists under the copied functional block.

If it is determined in step S56 that the subordinate functional block is not a copy (step S56;
No), it is determined whether or not a manual connection process for the subordinate functional blocks has been instructed (step S59).

In the determination in step S59, if the manual connection of the subordinate functional blocks is instructed (step S59; Yes), the process proceeds to the manual connection processing of the functional blocks (step S60). In this case, the functional block 1 which is the first functional block designated as the connection target or the connection deletion target is passed to the manual connection process of the functional block shown in FIG. 41 (step S61). Further, the function block 2 which is the second function block designated as the connection target or the connection deletion target and the connection type are passed to the manual connection process of the function block (step S62).
Here, connection addition or connection deletion is designated as the connection type. In addition, the manual connection processing of the functional blocks is performed by the functional block manual association processing unit 123g of the functional block that is being edited.

Here, the manual connection processing of the functional blocks will be described with reference to FIG. First, it is determined whether or not the connection type passed in step S62 from the control sequence editing process is connection addition (step S).
111).

If it is determined in step S111 that the connection type passed in step S62 is connection addition (step S111; Yes), the connection destination function block addition processing 122c of the function block being edited
Array data 121 of the connection destination functional block address storage variable of the functional block 1 designated in step S61
The functional block 2 designated by i and designated in the process of step S62 is added (step S112).

Next, in step S62, the connection source function block addition processing 122b of the function block being edited is performed.
The specified function block 1 is added to the array data 121h of the connection source function block address storage variable of the function block 2 specified by the process (step S113).

On the other hand, in the determination of step S111,
When the connection type passed in step S62 is not connection addition (step S111; No), it is determined whether or not the connection type passed in the process of step S62 from the control sequence editing process is connection deletion. (Step S114).

In the determination of step S114, if the connection type passed in the process of step S62 is connection deletion (step S114; Yes), the connection source function block deletion process 122 of the function block being edited 122
d and the connection destination functional block deletion processing, step S6
The relationship between the array data 121h of the connection source function block address storage variables of the function block 1 specified in 1 and the array data 121i of the connection destination function block address storage variables of the function block 1 specified in step S62 is deleted (step S115).

Further, the relationship between the designated function block 1 based on the connection source function block address storage variable array data 121h and the connection destination function block address storage variable array data 121i of the function block 2 designated in step S62. Is deleted (step S11
6).

Subsequently, the edit screen display process is performed to redisplay the screen (step S117). As a result, when the screen is displayed again, the connection relationship of the functional block to which the connection has been added or deleted has been changed, so that the updated connection line is displayed.

Finally, the function block automatic association processing will be described.

It is troublesome for the operator to manually connect the above-described functional blocks when adding the functional blocks when editing the control sequence. Therefore, in the present embodiment, when the functional blocks are added, when the arrangement positions of the functional blocks on the edit screen correspond to the specified pattern, the two functional blocks are automatically connected.

42 to 44 show patterns for performing automatic connection (conditions and state after automatic connection).

As a first pattern, as shown by reference numeral 1900 in FIG. 42, when there is a functional block already above the position where a new functional block is added,
This is a case where automatic connection is performed and a state as indicated by reference numeral 1901 in FIG. 42 is obtained.

As a second pattern, as shown by reference numeral 1910 in FIG. 43, when there is already a functional block on the left side of the position where a new functional block is added, automatic connection is performed and This is a case where the state as indicated by reference numeral 1911 is established.

As the third pattern, reference numeral 1 in FIG. 44 is used.
As shown by 920, when there is already a functional block on the upper left side of the position where a new functional block is added, automatic connection is performed and a state as indicated by reference numeral 1921 in FIG. 44 is obtained.

FIG. 45 is a processing flowchart of the automatic association processing. As the automatic association processing, first, it is determined whether or not a functional block already exists on the newly added functional block and a functional block to which the upper functional block is connected exists (step S12).

Further, based on the array data 121i of the connection destination function block address storage variable of the upper function block, it is determined whether or not the connection destination function block exists.

If it is determined in step S121 that a functional block already exists on the newly added functional block and a functional block to which the upper functional block is connected exists (step S121; Yes).
s), by the connection source function block addition processing 122b of the function block being edited, the connection source function block address of the newly added function block is stored in the array data of the storage variable, and the address of the upper function block on the main storage device 103 Is added (step S122).

Next, by the connection destination function block addition processing 122c of the function block being edited, the main block corresponding to the function block newly added to the array data 121i of the connection destination function block address storage variable of the upper function block is added. The address on the storage device 103 is added and the automatic connection is terminated (step S123).

When it is determined in step S2000 that the functional block does not exist above the newly added functional block or the functional block to which the upper functional block is connected does not exist (step S121; N).
o) It is determined whether or not a functional block already exists on the left side of the newly added functional block, and the connected functional block exists on the left functional block (step S124).

That is, it is determined whether or not a functional block already exists on the left of the newly added functional block, based on the array data 121b of the lower functional block address storage variable of the functional block being edited. Further, it is determined from the array data 121i of the connection destination function block address storage variable of the left function block whether or not the connection destination function block exists.

If it is determined in step S124 that the newly added functional block already has a functional block on the left side and the functional block on the left side has a connection destination functional block (step S124; Yes).
s), by the connection source function block addition processing 122b of the function block being edited, the main storage device 1 corresponding to the function block on the left side in the array data 121h of the connection source function block address storage variable of the newly added function block
The address on 03 is added (step S125).

Next, the function newly added to the array data 121i of the connection destination function block address storage variable of the left function block by the connection destination function block addition processing 122c (see FIG. 4) of the function block being edited. The address on the main storage device 103 corresponding to the block is added to terminate the automatic connection (step S126).

Further, in the determination of step S124,
If there is no function block on the left side of the newly added function block, or if there is no connection destination function block on the left function block (step S12).
4; No), it is determined whether or not the functional block already exists in the upper left of the newly added functional block, and the functional block of the connection destination exists in the upper left functional block (step S127).

That is, it is determined whether or not the functional block already exists in the upper left of the newly added functional block based on the array data 121b of the lower functional block address storage variable of the functional block being edited. Further, it is determined from the array data 121i of the connection destination function block address storage variable of the upper left function block whether or not the connection destination function block exists.

If it is determined in step S127 that the newly added functional block already has a functional block in the upper left and the upper left functional block has a connection destination functional block (step S127; Ye).
s), by the connection source function block addition processing 122b of the function block being edited, the main storage device corresponding to the function block on the upper left side in the array data 121h of the connection source function block address storage variable of the newly added function block. The address on FIG. 103 is added (step S12).

Subsequently, by the connection destination function block addition processing 122c of the function block being edited, the new function block is added to the array data 121i of the connection destination function block address storage variable of the upper left function block. The address on the main storage device 103 is added and the automatic connection is terminated (step S129).

If it is determined in step S127 that the newly added function block does not have a function block in the upper left, or if the upper left function block has no connection destination function block (step S127; N).
o) Assuming that the operator intentionally added a functional block to a position where automatic connection is not performed, automatic connection is not performed.

As described above, the automatic connection processing described above can save the operator the trouble of connecting the functional blocks, which tends to be complicated.

Here, an example of the display when the automatic connection is made will be described with reference to FIGS. 46 to 53.

Next, the effect of this embodiment will be described. In this embodiment, the function block 120 represents all the functions of the control task group, control task, block sequence, and actuator operation. Further, a hierarchical structure is realized by storing the subordinate functional blocks and the upper functional blocks by the array data 121b of the lower functional block address storage variables and the upper functional block address storage variable data 121c of each functional block.

Therefore, the operating system 10
As long as the specifications of 1 and the main memory 103 permit, a large number of hierarchical structures can be configured, and flexible design according to the design stage and design method of the machine control sequence becomes possible.

54 to 56 are examples of the edit screen of this embodiment.

According to this embodiment, as shown in FIG.
With the edit command screen 2200, it is possible to arrange the function blocks on the edit screen with a specified function and to connect the function blocks. Further, the setting value edit screen 2210 allows the setting value of the selected functional block to be edited. Then, the highest-level functional block is automatically generated by the activation of the editing program, and the highest-level functional block editing screen 2230 is displayed. This edit screen is the edit screen of the control task group.

Further, in this embodiment, one or a plurality of functional blocks as control tasks are arranged on the highest functional block edit screen. Therefore, by the functional block addition processing unit 123b of the functional block editing processing unit 123,
A functional block as a control task is subordinate to the highest functional block, and the block data section 12 of the highest functional block
Array data 1 of lower functional block address storage variable of 1
21b and the uppermost functional block is stored in the upper functional block address storage variable data 121c of the block data part 121 of the lower functional block to realize a hierarchical structure.

Also, as shown in FIG. 55, control task 1
When the editing screen of the functional block 2240 is displayed, the lower-level functional block drawing process 122a of the block processing unit 122 of the corresponding functional block from the lower-level functional block address storage variable data 121b of the highest level functional block causes the editing screen 2310 of the control task 1 to be displayed. Is displayed. Further, the functional block connection line drawing processing unit 123a of the editing processing unit 123
Displays the connecting line between the function blocks.

Similarly, when the edit screen of the functional block 2320 corresponding to the process 1 of the edit screen 2310 of the control task 1 is displayed, the edit screen 2430 corresponding to the process 1 is displayed as shown in FIG.

In FIG. 56, the highest functional block,
The highest-level functional block edit screen 2400, the control task 1 edit screen 2420, and the process 1 edit screen 2430 corresponding to each of the control task 1 under the highest-level function block and the process 1 under the control task 1 are displayed hierarchically. There is. Further, on the processing position edit screen 2430, the functional blocks under the processing 1 are hierarchically displayed, and the actuator operation 1 to the actuator operation 9 are displayed including the connecting lines.

In the example of the above screen, actuator operation 1
56 (reference numeral 2440 in FIG. 56) is selected to display the setting value corresponding to the setting value edit screen 2410.

As described above, by providing each functional block with the array data 121b of the lower functional block address storage variables and the upper functional block storage variable data 121c, it is possible to distribute the management of the functional blocks by the hierarchical structure. It is possible to realize efficient management of blocks.

Further, by hierarchizing the operations in one control task, a complicated sequence is not displayed on the screen at one time, so that it is possible to provide an edit screen which is easy for the operator to see.

Furthermore, the connecting lines between the functional blocks are shown in FIG.
Through the pattern shown in FIG. 53, the functional block connection line drawing processing unit 123a of the edit processing unit 123 of the functional block displaying the edit screen is stored in the lower order functional block address storage variable array data 121b. Since the connection line is drawn based on the function block display grid storage variable data 121j of the function block, the operator can freely change the position of the function block once connected.

Also, since the basic functional block connection is automatically performed by the functional block automatic association processing section 123f of the functional block edit processing section 123, the operator can reduce the complicated operation of connecting the functional blocks. You can

When the hierarchy becomes complicated as a multi-stage layer structure, the hierarchy structure can be visually confirmed on the hierarchy structure display screen as shown in FIG. In the case of this embodiment, there are control task 1 to control task 6 under the control task group 2501.
Processing 1 (reference numeral 2 in FIG. 25) under the reference numeral 2502)
503), processing 2, processing 3, ..., There are a plurality of block sequences, and there is an actuator operation 1 to an actuator operation 9 under the processing 1.

In the above description, the computer 10
The description has been made assuming that the control program for 0 to function as the control sequence editing device is stored in the ROM or the like in advance. However, these control programs are recorded in an external recording device such as a hard disk and activated, It is also possible to record these control programs on a removable recording medium such as an optical disk for installation, or to download and install them via a network. When downloading,
It is also possible to download each time it is executed. Further, a computer-readable recording medium such as a ROM can be configured to be replaceable.

[0249]

According to the present invention, the control sequence can be edited in a hierarchical structure, and the operator can easily understand the processing contents structurally.

Further, since each functional block can perform the editing process on the lower functional block, the lower functional block can be directly edited in the functional block being edited, and the hierarchical structure is traced from the uppermost functional block. Can be edited without

Furthermore, the functional blocks can be freely arranged on the edit screen.

Furthermore, the functional blocks on the edit screen and their connection relationships can be graphically displayed, and the operator can easily understand the control sequence.

Further, since the transition (flow) of the control procedure is only for the functional blocks connected by the connecting lines, even if there is an incomplete portion of the mechanism, the connecting lines of the incomplete functional blocks are If removed and connected to the functional block of the part where the mechanism is completed, it is possible to evaluate the completed mechanism without deleting the processing of the created functional block.

Further, since each functional block can be freely arranged on the screen, for example, an evaluation process is created near the edge of the screen, and the evaluation process is freely executed by connecting the connection lines at the time of evaluation. It can also be removed or removed.
