Maintenance Section 8-2
8-2-3 Replacing Units
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 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.
Note Before replacing a Unit, always stop Network communications and turn OFF
the power to all the nodes in the Network.
Settings after
Replacing a Unit
After replacing a Unit, set the new Unit's switches to the same settings that
were on the old Unit. Connect the same model of DeviceNet Communications
Unit to the Temperature Controllers as the previous Unit.
Note 1. By backing up the settings of the DeviceNet Communications Unit and the
Temperature Controllers, the settings can be reset in a batch. For details
on the device parameters upload and download functions, refer to the De-
viceNet Configurator Ver. 2
@
Operation Manual (W382).
2. When replacing a Temperature Controller, the DeviceNet Communications
Unit copy mode can be used to easily reset the Temperature Controller on-
site without requiring the Configurator. For details, refer to Reading/Writing
Temperature Controller Settings Using Copy Mode below.

Using Copy Mode
The DeviceNet Communications Unit has a copy function that can read or
write the setting parameters of all the Temperature Controllers connected to
the Unit in a batch (the read setting parameters are recorded in the DeviceNet
Communications Unit).
When a Temperature Controller has been replaced, the copy function allows
the Temperature Controller to be easily reset onsite without using a Configu-
rator. The copy function can read or write the following setting parameters of
the Temperature Controllers.
Note 1. Use the E5ZN-SDL Setting Display Unit to back up data when other areas
require setting.
2. If the system using the DeviceNet Communications Unit starts up normally,
use the copy function to read the Temperature Controller setting parame-
ters at the same time as saving the device parameters with the Configura-
tor.
