PURPOSE:To reduce the program capacity and also to omit production of a program in accordance with the action of a drive part each time, by using a single reentrant program to constitute a means for control of plural drive parts of a process controller using a microcomputer. CONSTITUTION:The control signal supplied from a keyboard 2 is applied to a control unit 1 and the output signal of the unit 1 is sent to the 1st-n-th input/output control parts 4-5. The 1st drive part 6 and the 1st detector 8 are connected to the part 4; while the n-th drive part 7 and the 1st detector 9 are connected to the part 5 respectively. The results of detection obtained by both detectors 8 and 9 are fed back to the unit 1 via the parts 4 and 5. Then the output of the unit 1 is displayed on a CRT 3. Thus plural control tasks can be processed in time division. This omits production of individual programs accordant with each control form. |
