Replacing Controllers
The Network consists of the DeviceNet Master Unit and Slave Units. The
entire network is affected when a Unit is faulty, so a faulty Unit must be
repaired or replaced quickly. We recommend having spare Units available to
restore Network operation as quickly as possible.
Precautions
Observe the following precautions when replacing a faulty Controller.
• After replacement make sure that there are no errors with the new Con-
troller.
• When a Controller is being returned for repair, attach a sheet of paper
detailing the problem and return the Controller to your OMRON dealer.
• If there is a faulty contact, try wiping the contact with a clean, lint-free
cloth dampened with alcohol.
Note
Before replacing a Controller, always stop Network communications and turn
OFF the power to all the nodes in the Network.
