DeviceNet Node Commissioning
Introduction
EC4 Current Monitoring 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 the EC4
Current Monitoring Relay 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 and later)
Use the following steps to commission the card.
1.
Set the node address switches.
IMPORTANT
The following recommendations are intended to ensure a trouble-free
startup and operation:
1. Use the node commissioning tool in RSNetWorx or the E3 programming and
control terminal when modifying the E3’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.
2. Ensure that you have the most current configuration information prior to saving an
RSNetWorx configuration file.
3. If you intend to employ the ADR function of the DeviceNet scanner, ensure that
the device configuration is as you intend it BEFORE saving to memory.
4. Be aware that the “Restore Device Defaults” button in RSNetWorx will reset the
EC4 Current Monitoring 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.
