Error when using PID and SCL

Vudv

I use OB1 to control DI / DO it works well.
But when I add OB35 to PID control, It does not work, Please let me know why?

Thank for help!

What do you mean by "PID Controller doesn't work"?Did you try to check controller in manual mode while COM_RST is disable! The other point to be check is "why did not you use the FB41 from PID library in STEP 7".You use the FB41 via SCL Source!!!!

Thank you for answering me. But what I want to say is why when I download to the PLC, It errors as in the attached file.

Dear Sir

Please help me to check why when I use the address ET200M of the I/O Analog to error?
You can see in Network 3 and Network 4 in OB35.

Thanks!

Dear Sir,

I tried to change more than one address, but are not active.
but why address of DI/DO it works good?

Thanks!

1. You test modules in central rack
2. You test digital signals on PROFINET IO
3. You test it with a DP Slave with same analog module

The problem may come from combination of PROFINET IO plus analog modules both in range of process image and even peripheral addresses.This is a problem that the software developers should answer it.Please try it here (Support Request).
