hi, IO-Error with Error-ID 494D has been discussed many times here in forum. Search for 'Event ID 16# 494D' For me it always seems to be a problem with the backplane-bus. But the best would be, contact Siemens by starting a Support Request. They could give you more information on this error with the coding from the diagnostic buffer: No relevance for user (Z2): 0050 (Z3): 4555 (Coding: 16# 494D FF44 C000 0000 0050 4555) hope this helps, regards, |
