Hello experts. I am using S7400 PLC and programming it in TIA V13 SP1. I am getting a red light at EXTF and in online diagnostic it shows I/O accesses error. I have attached the notepad format of the error. Can someone tell me the cause of the problem. from the error I though it has to do something with FC 2, but I don't have FC 2 in my program. Hardware config - PM->CPU(412 2 pndp)->32bit IM->32bit IM->16bit OM->16bit OM->16bit OM-> 8X13bit AI-> 8X13 bit AO AttachmentDiagnostics.txt (263 Downloads) |

maybe you have a FC2 online? the program is trying is read/write PIW/PQW 528-540. Do this addresses exist? Please also update your internal clock. it says its a log from 1994. Have you searched a solution with SIOS search engine? https://support.industry.siemens.com/tf/ww/en/posts/i-o-access-error-writing/154888/ There are several other threads with this problem |
