DeviceNet™ Node Commissioning
Introduction
E3 Overload Relays are shipped with a default software node address (MAC ID)
setting of 63 and the data rate set to Autobaud. Each device on a DeviceNet
network must have a unique node address which can be set to a value from 0 to
63. Keep in mind that most DeviceNet systems use address 0 for the master
device (Scanner) and node address 63 should be left vacant for introduction of
new slave devices. The node address and data rate for Series B and later E3
Overload Relays can be changed using software or by setting the hardware
switches that reside on the front of each unit. While both methods yield the same
result, it is a good practice to choose one method and deploy it throughout the
system.
Setting the Hardware Switches (Series B & Later)
Use the following steps to commission the card.
1. Set the node address switches. Use the table below to assist you.
IMPORTANT The following recommendations are intended to ensure a trouble-free
startup and operation:
• Use the node commissioning tool in RSNetWorx™ or the E3
programming and control terminal when modifying the E3 Overload
Relay’s node address. Do not use the “General” tab found in the
product window in RSNetWorx. The node commissioning tool ensures
that the device goes through a hard reset and requires the user to
upload the most current parameter information from the device prior
to making configuration changes.
• Ensure that you have the most current configuration information prior
to saving a RSNetWorx configuration file.
• If you intend to employ the automatic device recovery (ADR) function
of the DeviceNet scanner, ensure that the device configuration is as
you intend it before saving to memory.
• Be aware that the “Restore Device Defaults” button in RSNetWorx
will reset the E3 Overload Relay’s node address setting to 63. For
Series B and later devices, the hardware node address switches take
precedence over the software node address setting.
