[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

The system configuration of this embodiment is shown in FIG. This system includes an operator console 1, a central processing unit 2, a disk 3, a tablet 4, a graphic terminal 5 connected to the tablet 4, an XY plotter 6, and these devices 1, 2, 3, 5, 6, and mutually. It is composed of a bus 7 to be connected. The operator console 1 mainly inputs the name of equipment to be designed and the names of devices constituting the equipment, and sequentially designates standard operation circuits corresponding to a plurality of operations of the equipment. . In the central processing unit 2, when a standard operating circuit is designated via the operator console 1, operating circuit information representing this operating circuit is stored in the standard operating circuit information group stored in advance in the disk 3. Read out from the above, and organized according to a predetermined operation function, and further the organized operation circuit information is organized according to a predetermined device code order. The knitting process will be described in detail later. Further, in the central processing unit 2, when the tablet 4 is operated by an operator to make corrections or changes to the equipment circuit obtained by the above-mentioned knitting, processing for correction or change of the equipment circuit is performed according to this operation. Finally, the desired equipment circuit is finally drawn by the XY plotter 6.

FIG. 3 shows a flow of the operation of the system having the above configuration.

First, the operator operates the operator console 1 to input the name of the facility to be designed (reference numeral 10 in the figure).
1). Next, by the same operator operation, the name of one of the plurality of devices constituting this equipment is input (1
02).

Next, preparation is made to edit the operation circuit corresponding to the operation of the device (103). This operation circuit editing preparation consists of the following steps. Specifically, as shown in FIG. 4, first, the operation circuit name of 1 is input through the operator console 1 (1031). , A standard operating circuit information group stored in advance as a standard circuit file in the disk 3 is searched (1032), and it is determined whether or not there is operating circuit information corresponding to the input operating circuit name. (1033) If present, the operating circuit information is written to the disk 3 (1034), and the operating circuit editing preparation is completed. On the other hand, when the corresponding operation circuit information does not exist (for example, due to an operator operation error), the operation circuit name is newly input (1031), and the operation circuit is edited by writing this circuit information (1034). Preparation is complete.

Next, an operator operates the operator console 1 to instruct whether to add a new operation circuit (10
4).

When adding, the operation circuit editing preparation (103) is repeated for the number of circuits to be added.

Then, when all the circuits to be added are written in the disk 3, set editing I is next performed (105). This set edit I consists of the steps of creating tables I, II, III, and IV. As shown in FIG. 5, table I is created by circuit division (1051) and table II is created by common lines. (1052), creation of table III by card number (1053), and creation of table IV by function code (1054). The creation of these tables I, II, III, and IV will be described taking as an example the case where the operation circuit A and the operation circuit B as shown in FIG. 6 are combined. First, regarding the creation of the table I by circuit division, Numbers representing circuit division 31, 20, 10, 2
Enter the common line, card number, device code, and circuit existing address for each 1 and 32. For example, the table I created for the circuit section number 32 has the structure shown in FIG. Next, regarding the production of the table II by the common line, the produced table I is further divided into groups for each common line, and for example, the circuit division number 32 shown in FIG. 7 has a configuration as shown in FIG. Table II. Further, the created table II is divided into groups for each card number.
No. is assigned no card number, and is therefore a table III having the same configuration as the table II in FIG. Furthermore, the created table III is divided into groups according to the function code of the device code (for example, X in the device code CR1X corresponds). Table IV based on this function code is created in accordance with a predetermined priority order. An example of this priority order is as shown in FIG. 10, and this priority order table is stored in the disk 3 in advance. Then, for example, for the circuit division number 32, a table IV having a configuration as shown in FIG. 9 is used. These tables I, II, III and IV are written on the disc 3.

Next, the operator console 1 is operated to give a command as to whether or not to add a new device (106). When adding, a device name is input (102) again.

When the set edit I (105) is completed for all the devices constituting the facility to be designed, the set edit II is next performed (107). This set editing II performs a plurality of operations as shown in FIG. 11. First, the name of the equipment of the equipment to be designed and the order of connection between the equipments are input through the operator console 1 (1071). If there is an input error such as the device name (1072), the device name and the connection order are input again (1071). On the other hand, if the above-mentioned input is correctly made, it is determined based on the operation of the operator console 1 whether or not a device is added next. If no device is added, the device is connected (however, not only the final connection but also completion at an early stage of the equipment), and the equipment circuit after the connection is a disk. Written in 3 (107
4).

Next, the circuit is changed (108) for the equipment circuit after the set editing II (107). This circuit change is performed by a plurality of operations as shown in FIG.
Whether or not to add a circuit is determined based on the operation of the operator console 1 (1081), and if it is added, the circuit is added (1082). If the circuit is added or not, then the circuit is deleted or not. Judgment is made based on the operation of the operator console 1 (1083), if it is to be deleted, it is deleted (1084), and after this deletion or if not deleted, it is judged based on the operator's operation whether the circuit should be replaced next (1085), when the replacement is performed, the replacement is performed (1086), and after the replacement or when the replacement is not performed, it is determined based on the operator's operation whether or not the contact is added next (108).
7) If it is added, it is added (1088), and after this addition or if it is not added, it is determined based on the operator's operation whether or not to delete the contact next (1089).
If it is to be deleted, it is deleted (1090), and if it is not deleted after this deletion (1081 to 109).
0) is repeated based on the operator's operation, and if it is repeated, the process returns to the circuit addition judgment (1081),
After this repetition or when not repeated, all the circuit changing operations are completed.

Then, when the circuit change (108) is completed, the equipment circuit, that is, the sequence circuit is arranged on the XY plotter 6 based on the operation circuit information on the disk 3 which is first arranged in the order of the operation function and further arranged in the order of the function code as described above. It is drawn by.

In the above system, the operator console 1 corresponds to an input device and a display device, the central processing unit 2 corresponds to a processing device, the disk 3 corresponds to a storage device, and the tablet 4 corresponds to a designation device. The circuit division corresponds to the function, and the common line, the card number, and the function code correspond to the function information.

[Effects of the Invention] As described above, according to the present invention, the operator only needs to specify various operations necessary for the equipment of the equipment to be designed.
A standard sequence circuit for the equipment can be designed. That is, it is not necessary to decompose each operation required for the device into functions and individually extract the circuits corresponding to the respective functions.

In addition, the processing device divides each extracted operation circuit information for each function, collects and organizes each function, and rearranges based on the device information. Therefore, the operator can easily find an overlapping portion, an unnecessary portion, etc. of the extracted operation circuit information.

That is, if the extracted operating circuit information is simply listed, a great amount of labor is required to search for an overlapping portion or an unnecessary portion of the operating circuit information, but the present invention prevents such a situation. Thus, the editing of the operating circuit information can be further facilitated.

Therefore, according to the present invention, the labor for editing the sequence circuit can be dramatically reduced and the working time can be shortened.
