Dear User/Expert, We are using PCS7 6.1 and have encountered a problem.
Our S7-400H CPU reports "OB40 not loaded". We do not know how to trace the fault? What is causing this? We use ET200M I/O and Y-LINK and now also an "intelligent slave". could the intelligent slave have something to do with this? We have replaced the CPUs but that didn´t help. Please check the attached file Regards Robert AttachmentEvent 3xA1 and Diagnostic.pdf (283 Downloads) |
