Third modification to the program

5.3.1

On-delay timer

Objective:
In the following program modification, you
insert an on-delay timer in exercise
program 1.
When input I0.3 (S3) is activated on the
simulator, a waiting time is started.
Output Q0.0, and thus the motor, is not
activated until the waiting time has
expired.
No wiring work on the PLC is required for
the additional timer function.
All necessary switches and actuators are
already wired. The timer relay is replaced
by a PLC timer function.
