Hello everyone, I have problem with my S7-400. My CPU is going to STOP suddenly. When I check to diagnostic buffer it said "Event ID 16# 2942 I/O access error, reading". I also attached my complete diagnostic buffer. My question is : 1. what actually happen with my CPU and make I/O Access Error happen? 2. why its going to STOP even i have requested OB (OB122) ? I think this requested OB is to prevent CPU STOP when error happen. AttachmentDiagnose Strand 2E PLC.txt (295 Downloads) |
