Hello everyone...

I am working on a project and I have used SCL language to create the FB. Now the problem is I have used timers in the FB. First, all was working fine. But as the complexity of the project increased and I have added more FB's and DB's to the project after a while timers in the FB's stopped working. The timer doesn't start even if the IN is true. At this movement, I am having the following problems-

1. Timers in FB are not starting after the IN is true.
2. After some changes in the program, CPU outputs in not turning on, even in online monitoring it shows on but in reality the output is off. whereas the expansion module outputs are working fine.
3. I tried resetting the CPU but no solution.

I tried using different instances of timers and each time after the timer is on I reset the timer by USING 'RESET_TIMER('....')'.

My CPU is 1212C 6ES7 212-1AE31-0XB0 FW-3.0

using TIA V15.

Could anyone give me any clue of how to resolve this problem?

I have attached some pictures of my projects here.

Thanks in advance.

Split from Timers not work in SCL.

Please don't post twice for the same problem.
