dumb question
(OP)
Hello
First time poster looking for advice on a PLC program.
Goal
1. record time a sensor is on
2. delay signal for 3 seconds
3. send signal to motor and have it run for as long as the sensor did
Should I use a retentive time or use both on and off delays?
thank you!

RE: dumb question
On the transition from ON to OFF copy the "Sensor ON Time" elapsed time to the setpoint of the "Motor Run Timer".
Clear the "Sensor ON Timer" elapsed time.
Wait 3 seconds "Delay Timer" then run the motor until "Motor Run Timer" expires.
Hope this helps
Roy
