Replacing a secondary PLC-CPM
ATTENTION: Replacing a secondary CPM can be performed
while on-process or off-process.
We recommend that you proceed with extreme caution
whenever replacing any component in a control system. Be
sure the system is offline or in a safe operating mode.
Component replacements may also require firmware update.
Wear an ESD wrist strap and observe static precautions
You will need a #2 Phillips screwdriver.
To replace a secondary PLC-CPM
1. [Optional] It is recommended to disable and prevent
synchronization first by issuing the redundancy disable
synchronization command from ControlEdge Builder.
2. Using an external (user-supplied) switch, disconnect the power
supply in the rack (associated with the CPM to be replaced) from
the source main power.
3. Observe where communications cables are plugged into the CPM
to be replaced, and if necessary, tag them to identify their
functions. Unplug all communications cables.
4. At the top and bottom of the module to be replaced, loosen the
captured screws that secure the module in the rack, and remove
the CPM from the rack. (Note that an up/down rocking motion
helps with removal of the module).
5. At the top and bottom of the module, loosen the captured screws
that secure the module in the rack, and remove the CPM from the
rack.
6. Ensure that the new CPM is properly aligned with the slot guides,
insert the new CPM in the rack, and secure it in place with the
captured screws at top and bottom of the module.
7. Re-install communications cables.
