Hello, Denis, Look at the topics below - they are similar to your request: IO access error in S7 -1200 CPU I/O ACCESS ERROR WHEN UPDATING THE PROCESS IMAGE INPUT TABLE If you summarize the topics above then (use the search on the forum - this is useful))): 1. look in HW which module use the Adress 12 (New I/O access error during process image update output 12). 2. Did you try to compile (Rebuild All) (hardware part) and download hardware to CPU? 3. Try to change the order of the modules, to look what happens then (do after - Rebuild ALL). 4. Check FW modules in the project and FW real modules Maybe required FW-Update. The newest FW can be downloaded from Siemens Web site))) 5. Modules movement might correct the problem if more care is given to sliding the bus connectors between modules. Are all modules on the same DIN rail? 6. Are adjacent modules touching, or is there any air gap between them? Check connection quality. Check everything, let me know - if nothing helps - we will help as we can) |
