POTENTIAL OPERATING ISSUES
Part. No. 2400M2501_6 Touchpoint Pro
149 Technical Handbook
Operation failed; the intended
operation is not allowed for the
current I/O Module state.
These errors may
occur if configuration
of the module or its
channels was
interrupted, leaving
the module in an
undetermined state
Depending on the intended operation, either:
Restart the configuration for the module, or
from the configuration screen, remove the
module and restart commissioning, or Force
the module to Normal state
The I/O Module could not be
found on the network (unknown
UDID).
The I/O Module could not be
found on the network (unknown
SDID).
Operation failed; I/O Module
state is invalid.
State Change operation failed;
could not communicate with I/O
Module.
Potential issue with
the ring network
connection, or
damaged/faulty I/O
Module
1. Check the Active Events screen for any
reported failure of the ring communication. In
this case, refer to Error 37 – Ring
communication failed.
2. Check that the I/O Module is properly seated
on the DIN rail.
3. If the error persists, remove the module and
check for any damage to the connector on the
DIN rail.
4. In this case, it may be possible to move the
module to another slot.
5. If the connector is damaged, contact your
local representative to obtain a replacement
DIN rail PCB assembly.
6. If no damage is apparent to the connector
and the module fails to operate in another slot,
then the module may be faulty. Follow the
procedure in Maintenance, Replace an I/O
Module to replace it.
