Abstract

PURPOSE:To operate each PC easily with a time difference by setting an exclusive start interlock flag to each programmable controller with a timer having separate time limit when an operation command signal is 0. CONSTITUTION:In operation priority controller, each programmable controller (PC) obtains an operation command signal through the AND condition between signals 26-n6 inverted from the start interlock flag and start command signals 21-n1 while the programmable controller of equipment 20pc occupies a common equipment and is operated while other equipment is in standby of the occupancy. In this case, timers 25-n5 having different times set by a reset signal 23 and starting its operation after the operation of the equipment is finished are provided respectively to PCs, a start interlock flag (output of FF22) is set separately with a time difference. The start priority is given to each PC and a PC having the highest priority produces the operation command signal among the PCs in standby.
