Title:
SIGNAL CONTROL SYSTEM FOR PC
Document Type and Number:
Japanese Patent JPH05265518
Kind Code:
A
Abstract:
PURPOSE:To reduce the number of program step in a sequence program by providing a function perforating the synchronization control of an output signal in a PC(programmable controller). CONSTITUTION:Primary output signals DO1a, DO2a for which processings were performed in a sequence program, are temporarily stored in an output register 1 of an input/output control circuit IOC 24. Next, the synchronization control with output signals DI1, DI2 from a machine side is performed for the signals in a timing control circuit 2 of an I/O unit 26 and the signals are outputted as output signals DO1, DO2 to the machine side.
