Abstract
PURPOSE: To monitor a state without increasing the number of monitoring lines, by modulating the operation signal of each slave processor by slave processors at an independent frequency and then by sending the resulting signal to a master processor side.
CONSTITUTION: At each slave processor 2 side of ladder constitution, an operation monitoring circuit 21 is provided and an output 23 is generated according to whether an operation state monitoring signal 22 is abnormal or not and sent out to a master processor 1 via a transmitting and receiving circuit 24 by being frequency-modulated by the slave processors 2. Therefore, the master processor 1 side monitors only the modulation frequency to monitor the slave processors 2.
