7-3-3 Replacement of Units
A defective Unit may have an effect on the entire network communication
performance. Therefore it is important to immediately replace a defective Unit
in the network. It is recommended to have spare Units available to restore
network operation as quickly as possible.
Precautions Observe the following precautions when replacing a defective Unit:
•
After replacement, make sure that there are no errors with the new Unit.
•
When a Unit is being returned for repair, attach a sheet of paper detailing
the problem and return the Unit to your OMRON dealer.
•
If there is a faulty contact, try wiping the contact with a clean, lint-free
cloth dampened with alcohol.
After replacing a Unit, set the new Unit’s switches to the same settings as the
old Unit. If the Unit requires configuration data other than the predefined
connection set, store the settings in its non-volatile memory.
Hot swapping
The CANopen network allows connection and disconnection of nodes while
in operation. The node that is connected to the network will not be
operational until it has received the NMT command ‘Start_Remote_Node’.
Adding a new node to an existing configuration will most likely require
configuring of that node and the node(s) that it needs to communicate with.
Note Do not plug or unplug the C200HW-CORT21-V1 on the PLC backplane while
the PLC is powered. Doing so may result in damage to the Unit and/or the
PLC system.
