Is a remote Input module configured for I0? If so, before calling FB613 from OB30, make sure the remote input module is online. I recently had to add similar logic before accessing VFD telegram data and generating 1600 diagnostics entries in a very short period of time.

Communication was working fine since I made PLC to the STOP mode and after that it is not working Temporary CPU error: I/O read access error (I address 0) in FB 613 affecting OB 1 execution Incorrect address, operand ignored I don't know if this is important but I made and upgrade to TIA V18 Update 4. In attachment please find screens from TIA V18 Attachment (5).png (163 Downloads)
