Abstract

PURPOSE:To attain generation and change in a program operating a peripheral function unit without providing any program generating means at all by providing a sub-central processing means, a sub storage means and a switch means to each peripheral function means. CONSTITUTION:In generating a program of a PID peripheral means 41 and storing it, a switch command is inputted to a main central processing means 1, a switch request is given from the means 1 to a PID central processing means 41a to switch a switch means 41c. A program storage means 41b leaves the control of the means 41a by the switching operation of the means 41c and the program for PID control generated by a program generating means 3 is stored under control of the means 1. When the storage to the means 41b is finished, a reswitching request is given from the means 1 to the means 41a, the means 41a places the means 41b under it control, uses a new program for PID control to apply PID control. The operation is similar to other PID peripheral function means 42-4n.
