Corrective Action
Refer to the section Isolated
(lonely) Node.
Corrective Action
Check the secondary IOLINK
and/or IO Modules for proper
physical address.
In the C300 this is derived from the
Module's device Index, one partner
having an odd index and the other
having an even index.
1. Check IOLINK cable A 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
suspect link (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 via the I/O Link
Command "ENB_PERSWAP" from
the Main Tab
(c) Monitor the error counts.
