s7200 subroutines

I think I know where the problem lies. If you're talking about using a SR within the subroutine, I think you have defined the address of the SR as being an OUT vartype in the definition table. Try the same but define the SR address as vartype IN_OUT. That way the subroutine reads the status of the SR address before processing any instruction and writes the new status back after processing the SR.

Kind regards,

Makes sense what you say, but I think I found the problem. I used the same subroutine more than eight times!!! I changed this so that I have only 7 calls to the SBR nad it works fine. Changed it back to Nine times and had the same problem as before.

Thanks to u guys for the advice. Didnt know that there was a limit of eight on the SBR calls.

The only problem will be in the nesting depth, I think the block can only be called 8 times…..

Is this where I say “I told you so”? Just joking, glad you sorted it out!
