Corrective Action
1. Check IOLINK cable B from end
to end for proper connections.
2. Check the cable connectors at
the IOTAs and fix as needed.
3. Refer to the IOLINK Statistics for
the error counts to zero in on the
culprit (Primary IOLINK, secondary
IOLINK, or IOMs) and replace if
necessary.
Once a problem has been
identified and a fix is applied, verify
the fix by:
(a) Reset the Error counts through
the I/O Link Command
"RESET_ERRORS" from the Main
Tab, then
(b) Re-enable the Periodic Cable
Swap diagnostic through the I/O
Link Command "ENB_PERSWAP"
from the Main Tab
(c) Monitor the error counts.
