And a monitor unit 52 for performing monitoring.

Control program creating apparatus 30 of the present embodiment
Is basically configured as described above. Next, the operation thereof will be described.

In the I / O list editing section 40, a label name 81 and a comment 85 are set for the addresses 83 of the input relays and output coils to be used and stored in the data storage section 50 as a comment file. Logic chart editor 3
4, the comment area 72a, the label area 72b,
ON of address area 72c and limit switch
A block 70 composed of a state area 72d indicating the / OFF state is displayed on the display device 62, and each area 7d is displayed.
By setting data in 2a to 72d and establishing a logical expression, a logical chart 68 such as an interlock condition is created (FIG. 2). The logic chart editing unit 34 stores the created logic chart 68 in the data storage unit 50.

The operation program editing section 36 creates an operation program 80 by setting the step operation timing for each actuator set by the actuator editing section 38 (FIG. 3). Operating program editor 36
Stores the created operation program 80 in the data storage unit 50 as an operation program file.

The actuator editing section 38 designates a circuit pattern name 88 of the basic actuator circuit 86 (FIG. 6) created by the pattern circuit editing section 42, an actuator name 80a, a passive I / O 80b, and an active I / O 80b.
The actuator information 82 is created by setting an address such as / O80c in each actuator circuit 86 (FIG. 4). The actuator editing unit 38 stores the created actuator information 82 in the data storage unit 50 as an actuator information file.

The automatic generation section 46 creates a source program of the main part of the control program based on the operation program 80 created by the operation program editing section 36 and the actuator information 82 created by the actuator editing section 38. This source program is converted in the command word generation unit 48 into a control program composed of object level command words to which the logic chart 68 created by the logic chart editing unit 34 is added, and stored in the data storage unit 50.

The control program stored in the data storage unit 50 is transferred to the sequence controller 64 by the command transmission unit 54 via the communication unit 58. The sequence controller 64 controls the sequence of the object according to the transferred control program. Further, the sequence controller 64 detects the operation state of the target object and transfers the detected operation state to the monitor unit 52 via the communication unit 58.

The monitor data generator 10 includes a logic chart editor 34, an operation program editor 36, an actuator editor 38, a comment file 20 from the I / O list editor 40, a logic chart file, an operation program file 22, an actuator Based on the information file 24, monitor data including an address data file 26 and a screen display data file 28 is generated and stored in the data storage unit 50. On the other hand, the monitor unit 52 displays a display based on the address data file 26 and the screen display data file 28 stored in the data storage unit 50 and the operation state data of the object supplied from the sequence controller 64 via the communication unit 58. The display device 6 via the unit 56
2 displays the monitor screen shown in FIG. 7 in real time.

Next, the processing of the monitor data generator 10 according to the present embodiment will be described in more detail with reference to the functional block diagram of FIG. 8 and the flowchart of FIG.

First, the input means 12 reads data from the comment file 20 created by the I / O list editing section 40 and the actuator information file 24 created by the actuator editing section 38 (S1). Next, the input unit 12 reads data from the operation program file 22 created by the operation program editing unit 36 (S
2).

The address extracting means 14 extracts the address set in the operation program file 22. That is, the address extracting means 14 extracts only the address data from the data of the operation program file 22 of FIG. 10 as shown in FIG. 11 (S3). In this case, the address extraction means 14 determines whether the extracted address data is already extracted address data (S4), and if it is not extracted, outputs the address data to the address data file 26 ( S5).

On the other hand, the coordinate setting means 16 sorts the data read from the operation program file 22 by data type (S6) and sets respective display coordinates (S7). FIG. 10 illustrates three types of data. Data type is "5" (interlock confirmation)
In the case of (1), the X coordinate 1 is calculated from the data of the start time of the interlock condition. Since the position in the Y-axis direction where the interlock condition is displayed is fixed, the Y coordinate is set to a fixed value. Further, comment data corresponding to the address of the interlock condition is extracted from the comment file 20 and set. When the data type is "4" (step confirmation), the X coordinate 1 is calculated from the start time data, and the Y coordinate 1 is set from the actuator number data and the position data. When the data type is "1" (step command), the X coordinate 1 is calculated from the start time data, the X coordinate 2 is calculated from the end time data, and the Y coordinate 1 and the position data are calculated from the actuator number data and the position data. The Y coordinate 2 is calculated. As described above, the coordinate setting means 16 calculates the display position 94 of the interlock condition and the display position 92 of the progress state of each step command shown in FIG.
Set the coordinates such as.

The output means 18 is provided with the coordinate setting means 1.
The comment data is added to the data set in step 6 and output to the screen display data file 28 (S8, see FIG. 12).

Subsequently, the input means 12 determines whether or not the processing is the last data, and if not, returns to the operation program data reading processing (S2).
The process is continued (S9), and if the data is the last data, the process ends.

On the other hand, the monitor unit 52 displays the monitor screen shown in FIG. 7 based on the address data file 26 and the screen display data file 28 created as described above. In this case, the address data is displayed at the position set by the coordinate setting means 16 together with the comment data. Further, the monitor unit 52 blinks the interlock condition, the step number, and the like based on the operation state data transmitted from the sequence controller 64, so that the operation state of the object is displayed in real time.

[0024]

According to the monitor data creating apparatus of the present invention, the following effects can be obtained.

Since the monitor data creating apparatus of the present invention does not need to create a monitor program for each control program, the time and labor required for these operations can be reduced and the efficiency in designing and creating a control program can be improved. Can be. In addition, monitor data can be automatically created from data such as comment data, operation program data, and actuator information when a control program is created, so that inconsistency between the control program and the monitor screen does not occur, and reliability is improved. High monitoring can be realized.
