I'm using a T22H-NPN and am new to PLC programming. In my circuit when inputs 1 and 3 are both activated I need a timer that will activate output 1 for two seconds and then turn it off no matter how long inputs 1 and 3 are hot. A change in the status of inputs 1 and or 3 (loss of signal) would reset the timer so that if inputs 1 and 3 are activated again the timer would again activate output 1 for two seconds. Can you help an "old timer" learn a new trick?
