Abstract

PURPOSE:To simplify the main body of a control part and increase the extension properties for a sequence controller, by constituting the main body of the control part with central processing unit and providing a PROM, a PROM writer and a control switch into a peripheral machinery. CONSTITUTION:A control part main body 1 consists of a central processing unit including a central processing circuit 11, a process program storing ROM12, a sequence control program storing sequence memory 13, etc. A peripheral machinery 3 consists of a PROM writer unit including a PROM31, a PROM write processing program storing memory 32, a write processing control part 33, etc. Furthermore, a peripheral machinery 4 consists of a program input/output unit comprising a keyboard 43, etc. Thus the main body of a controller consists of the minimum central processing unit that is necessary for execution of a sequence control program, and other means are decentralized at the peripheral area. In such way, the controller main body can be simplfied, and the function can be easily enhanced with addition of peripheral devices.
