I would recommend the IEC timer, and then multi-instance it (ie instead of creating an additional instance DB, create an instance for it inside the FB calling it).
I successfully call a TON timer from SFB4 as per your instruction.
Now I have another problem.For simple timer we use S5Time but with this timerTON the input PT is in the form of TIME, now how I give S5time instead of TIme.I tried with MOVE but its not work properly.
