How to Check a M580 ERIO System for Cabling Errors CRC errors
... Both CRC and FCS are destination checks used to sure data as arrived intact. The number of errors should very low (less than 10) and never change unless a port is unplugged etc. On faulty network the error count will be in the 1000s and change every few minutes if not quicker. ...
