Soft Fail Message

Corrective Action
Partner Not Visible On
FTE
Indicates that the Fault Tolerant
Ethernet (FTE) communications with
redundant controller partner and FTE
network are lost.
Refer to the section
10.6 IOLINK block soft failures
Notifications which are generated by the controller identify Soft Failure conditions in the
IOLINK interface, when indicator is lit.
Table 15 IOLINK Block Soft Failures
Soft Fail Message
Condition when indicator is lit
Corrective Action
Duplicate IOL Address
Indicates a duplicate IOLink address
has been detected.
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.
IOL Channel A Failure
Indicates that Channel A of the
IOLink has failed.
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.
