DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying an image related to a control operation of a control device based on data transmitted from a control device such as a programmable controller, and to generate setting data for the display device. The present invention relates to a data creation device, a data creation method, and a recording medium that records a data creation program.

[0002]

2. Description of the Related Art Programmable controllers are used to sequentially control controlled devices.
Input devices such as switches and sensors and output devices such as electromagnetic switches, relays, solenoids, motors, and cylinders are connected to the programmable controller. This programmable controller controls a controlled device according to a control program created in advance.

Various devices are allocated to a memory in a programmable controller. here,
The device refers to an element such as a relay (an input relay, an output relay, an input / output relay, an auxiliary relay, etc.), a timer, a counter, a data memory, and the like used on the control program. The device includes, as data types, a bit device consisting of a 1-bit area on a memory (contacts of a relay, a counter, and a timer) and a word device consisting of one or more words on a memory (setting of a timer and a counter). Values, current values of timers and counters, data memory, etc.).

[0004] These devices are specified by device information including a device type and a device number.
That is, the address on the memory to which the device is assigned is specified using the device type and the device number. The device type represents the name of the device, and the device number is a number assigned to identify a plurality of devices of the same device type.

The state of the device changes with the control operation of the controlled device by the programmable controller. For example, ON / OFF of a bit device such as an input relay or a data value of a word device such as a data memory changes.

[0006] A display device is used to display the state of the device of the programmable controller. This display device is used not only for displaying the state of the device, but also for setting the state of the device of the programmable controller. In this case, an address on the memory of the programmable controller is specified using the device information, and a data value stored at the address of the memory is set as a control parameter.

In a production facility for controlling a controlled device using the above-mentioned programmable controller and display device,
It is necessary to change the operation content due to a change in the product. For this reason, the programmable controller usually changes the control parameters used to control the moving distance of the robot, the stroke value of the cylinder, the number of revolutions, etc. Are stored in an internal memory for each operation content together with name information for specifying the operation content such as the model number.

[0008] However, storing all control parameters corresponding to a plurality of operation contents in the programmable controller increases the burden on the programmable controller. In addition, it is difficult to determine which control parameters are stored in the programmable controller. The above control parameters are stored in the display device for each name information because they are not easily understood by the user.

With this, the operator selects the name information such as the model number of the product using the display device when necessary, and controls the control parameters stored in association with the name information from the display device. Writing to a controller and reading control parameters of selected name information from a programmable controller to a display device are performed.

[0010] Further, there has been developed a data creating apparatus for creating setting data indicating the correspondence between control parameters and device information for each name information. When creating setting data using this data creating apparatus, one or more device information is set for each name information, and a control parameter to be set for a device specified by each device information is input as a data value. I do. The setting data created for each name information in this way is transferred from the data creating device to the display device and stored in the memory. Then, the control parameters included in the setting data are transferred to the programmable controller, and stored at an address on the memory specified by the device information.

[0011]

As described above, when creating setting data to be transferred to a display device using a data creating device, a user needs to set device information. Specifically, a device type is input, and a device number is input.

However, various types of programmable controllers are provided by a plurality of manufacturers, and the rules for specifying device numbers are different for each manufacturer or for each type of programmable controller.

For example, in the case of a certain programmable controller model of a certain manufacturer, 0000
. 000001,00002... Are incremented by one. Further, in a programmable controller model of another manufacturer, the device is assigned a device number which is increased by 16 such as 00000001000003. In this case, for example, 00002 cannot be set as the device number. Therefore, the user needs to remember the device number specification rules for each maker or for each model of the programmable controller.

FIGS. 12 and 13 show examples of a device setting screen of a conventional data creating apparatus.

In the example shown in FIG.
In 0, the device type column 801 and the device number column 802
Is displayed. A number indicating a device type is input to a device type column 801, and a device number is input to a device number column 802 using a numeric button 803. In this case, the user needs to input a device number in accordance with a device number designation rule defined for each maker or model of a programmable controller.

In the example shown in FIG. 13 as well, a device type column 811 and a device number column 812 are displayed on the data setting screen 810. The number indicating the device type is input in the device type column 811, and the initial value “000” of the device number displayed in the device number column 812 is increased or decreased by one using the arrow buttons 813 and 814. Alternatively, a device number is input to the device number column 812 using the numeric buttons 815. When an “OK” button 816 is pressed, a device number is set.

At this time, if the user sets a device number that does not exist in the device number specification rules defined for each maker or each model of the programmable controller, an error occurs. Therefore, when the user inputs an erroneous device number that does not match the specification rule, the user can recognize that the device number is incorrect only when the “OK” button 816 is pressed.

As described above, when a device number is set in a conventional data creating apparatus, the device number must be set unless the user remembers the device number specification rules set for each manufacturer or each model of programmable controller. Can not do it.

An object of the present invention is to easily set a value of element information according to a rule defined for each model of a control device when setting data including element information such as device information and control parameters is created. An object of the present invention is to provide a data creation device, a data creation method, and a recording medium that records a data creation program.

Another object of the present invention is to easily set element information according to rules determined for each model of a control device when creating setting data including element information such as device information and control parameters. It is to provide a display device which can be used.

FIG. 9 is a diagram showing an example of a device display screen after setting device information on the device setting screen.

As shown in FIG. 9, the device display screen W1
In the device information display area DI, six pieces of device information set on the device setting screen W2 are displayed. In this state, the data value display area DV of “Record 00000”
A data value can be input as a control parameter in each of the fields.

The device information set in the device information display area DI of the device display screen W1 and the data value set in the record of the data value display area DV corresponding to each device information are stored in the RAM 360 as setting data. . The setting data stored in the RAM 360 is transmitted to the communication control unit 1 of the display device 100 via the communication control unit 310.
Sent to 10. The display device 100 includes a communication control unit 11
0 is stored in the SRAM 180
To memorize.

Further, the display device 100 includes the SRAM 18
The data value included in the setting data stored in “0” is transmitted to the communication control unit 210 of the programmable controller 200 via the communication control unit 110 as a control parameter. The programmable controller 200 sets the control parameter received by the communication control unit 210 to the address of the memory 230 specified by the corresponding device information.

Note that the setting data transmitted from the data creation device 300 to the display device 100 may include device number designation rule information. In this case, when the user changes the device information in the setting data on the display device 100, the device number is changed according to the device number specification rule determined for each model of the programmable controller 200 as shown in FIGS. Can be automatically increased or decreased.

FIGS. 10 and 11 are flowcharts showing the device number display processing in the data creation program.

First, the CPU 350 receives an input of the model name of the programmable controller 200 (step S1). In this case, when the user sets the model name of the programmable controller 200 in the model name setting column 600 of the device display screen W1 shown in FIG.
0 acquires the set model name.

Next, the CPU 350 accepts an input of a device type (step S2). In this case, when the user double-clicks on a desired column in the device information display area DI of the device display screen W1 shown in FIG. 4, a device setting screen W2 is displayed on the display 320. Then, the user sets the device setting screen W2 shown in FIGS.
When a device type is selected in the device type column 602, the CPU 350 acquires the selected device type.

Next, the CPU 350 acquires device number designation rule information corresponding to the input model name and device type from the RAM 360 (step S3).

Thereafter, CPU 350 accepts a device number increment operation (step S4). In this case, the user presses the arrow button 6 on the device setting screen W2.
When the user clicks on the buttons 05 and 606, the CPU 350 recognizes that the arrow buttons 605 and 606 have been clicked.

Then, the CPU 350 acquires the device number displayed in the device number column 603 of the device setting screen W2 (step S5). Device number column 603
Indicates an initial value.

Next, the CPU 350 divides the acquired device number into a plurality of check ranges based on the acquired device number designation rule information (step S6). For example, in the example of FIG. 8, the device number “458000” is set to the lower 4 digits of the check range C1 and the upper 2 digits of the check range C
Divide into two.

Further, the CPU 350 acquires the value of the first check range (step S7). In the example of FIG.
The value “8000” of the check range C1 is acquired.

Next, the CPU 350 adds 1 to the value of the check range (step S8). In the example of FIG. 8, 1 is added to the value “8000” of the check range C1,
“8001”.

Next, the CPU 350 determines whether or not the value of the check range has overflowed (step S9). In this case, when the value of the check range exceeds the range specified by the device number specification rule information, it is considered that an overflow has occurred. When the value of the check range overflows, an overflow flag indicating that the overflow has occurred is set and the value of the check range is set to 0 (step S10). In the example of FIGS. 7 and 8, when the value of the check range C1 becomes “8192”, the overflow flag is set and the value of the check range is set to “0000”. Step S9
If the value of the check range does not overflow, the process proceeds to step S11.

Further, CPU 350 determines whether or not the value of the check range is a valid value (step S).
11). If the value of the check range is a value that matches the device number specification rule information, it is regarded as a valid value, and if the value of the check range does not match the device number specification rule information, it is regarded as an invalid value. For example, in the examples of FIGS. 7 and 8, the value of the check range C1 is “0000” to
A value in the range of “8191” is regarded as a valid value,
If the value is out of the range of “0000” to “8191”, it is regarded as an invalid value. In the example of FIG. 6, the check range is 1
Therefore, if the last two digits of the device number are “00”, it is regarded as a valid value, and the last two digits of the device number are “00”.
If the value is other than, it is regarded as an invalid value.

If the value of the check range is an invalid value in step S11, the process returns to step S8, and steps S8 to S11 are performed until the value of the check range becomes a valid value.
Is repeated.

If the value of the check range is a valid value in step S11, it is determined whether or not the overflow flag is set (step S12). If the overflow flag is set, the overflow flag is cleared and the value of the next check range is obtained (step S13), and the process returns to step S8. In the examples of FIGS. 7 and 8, the overflow flag is cleared and the value “00” of the check range C2 is acquired. Then, the processing of steps S8 to S12 is repeated for the check range C2.

If the overflow flag is not set in step S12, the plurality of divided check ranges are combined and displayed in the device number column 602 (step S14). In the examples of FIGS. 7 and 8, the values of the check ranges C1 and C2 are combined and displayed in the device number column 602.

Thereafter, when the next increment operation is performed, the process returns to step S5, and returns to steps S5 to S5.
The process of S14 is repeated.

As described above, in the data generating apparatus 300 of the present embodiment, the programmable controller 2
Since the device number displayed in the device number column 603 of the device setting screen W2 is automatically increased or decreased according to a rule defined for each model of the programmable controller 200, the user can change the device number defined for each model of the programmable controller 200. It is possible to easily set an accurate device number without memorizing the rules.
