A block 70 including a status area 72d indicating the ON / OFF status is displayed on the display device 62, and each area 7
By setting data in 2a to 72d and formulating a logical expression, a logical chart 68 of interlock conditions and the like is created (FIG. 2). The logical chart editing unit 34 stores the created logical 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 unit 38 specifies the circuit pattern name 88 of the basic actuator circuit 86 (FIG. 6) created by the pattern circuit editing unit 42, the actuator name 80a, the passive I / O 80b, and the active I.
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.

Next, the processing of the monitor data generation unit 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. 9 by taking the monitor data generation by the operation program as an example.

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 means 12 reads data from the operation program file 22 created by the operation program editing section 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 according to the data type (S6), and sets the respective display coordinates (S7). FIG. 10 illustrates three types of data types. Data type is "5" (interlock confirmation)
In the case of, the X coordinate 1 is calculated from the start time data 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. Also, the comment data corresponding to the address of this 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), X coordinate 1 is calculated from the start time data, X coordinate 2 is calculated from the end time data, and Y coordinate 1 is calculated from the actuator number data and the position data. Y coordinate 2 is calculated respectively. As described above, the coordinate setting means 16 uses the control program data to display the interlock condition display position 94 and the step command progress state display position 92 shown in FIG.
Set the coordinates such as.

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

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