Abstract
PURPOSE: To simplify constitution to reduce the number of program processes by controlling a numeric operation processing unit so that this unit may be operated or stopped by a specific output of a logical operation processing unit.
CONSTITUTION: Program storage unit 1 stores a sequence porogram and a numeric operation program, and logical operation processing unit 2 scans and designates circularly addresses of storage unit 1 and reads and inputs stored programs repeatedly and inputs them to numeric operation processing unit 3 simultaneously. Unit 2 fetches signals, which correspond to logical states, from I/O units 4 and 5 through data bus d according to an input program, and sets the operation result to I/O unit 4. Then, flag register 6 stores the output of unit 2 temporarily, and the output is inputted to unit 3, thereby controlling operation and stop of unit 3 according to output contents.
