Dear user,
Clearly, you are using S7-Distributed safety and developing your logic with F-LAD.The problem is explained in the manual related to safety signal module(Attached file). In case of a wire breakage in S7-Distributed Safety, fail-safe value of 0 is written to process input image (PII). For each analog input module there is an automatically generated data block that contains some inputs to acknowledge any error or trigger re-integration and some outputs that indicate faults on any channel plus a DIAG for troubleshooting.I think your case can be solve by checking that DB plus proper wiring of module. SIMATIC Automation System S7-300 ET 200M Distributed I/O Device Fail-safe signal modulesI hope it helps, hdhosseini
