(0)  Dear experts please check the following circuit diagram.As I guess ,In the circuit a speed monitor used to sense the STOP status of PLC to activate the Emergency stop and stop the main hardrware like motors immediately. As I check the user program, the output is a copy of 1hz PLC's internal clock pulse.
