Timer inside FB Siemens S7 300

kindly help me to make a timer inside the FB S7 300

You can declare an input named timer, and just pass the timer into the FB.

Or you could use an IEC timer.

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).

HOW TO CREATE MULTIPLE INSTANCE
I tried timer TON in stat but this is not a valid entry

Look at the block folder on the back ground. You will have to add the SFB3/4/5 to your project from the library.

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.

Why not use time?

Time is an integer as milliseconds. So a integer value of 1000 is equal to 1s.

S5time uses the first two bits as a multiplier (10ms, 100ms, 1s and 10s).

You could convert the s5time to time but working with time is much easier.
