PURPOSE:To elevate a general use property of a programmer device, by connecting plural sequence control devices to one programmer device through a buffer device. CONSTITUTION:A control device for executing a process control is divided into sub- sequence control devices 212... and a master sequence control device 211. A number No is put to a minimum program unit of each block diagram which is displayed on a CRT, and it is called a sheet No. That which has collected several sheet Nos. is called a system No. An index memory relating to the sheet No, the system No and the subsequence control device is provided on a buffer device 31. An optional program can be selected by a sheet No and a system No designated by a programmer device 41. The program is stored in the buffer device and also is displayed on the CRT. Accordingly, a function related to a program display is executed by only one set. |
