„ DeviceNet Option Fault Monitors U6-98 and U6-99
The DeviceNet Option SI-N3 can declare the error/warning conditions via drive monitor parameters as shown in
Table 22 .
Table 22 DeviceNet Option Fault Monitor Descriptions
Two drive monitor parameters, U6-98 (OPTN LATCH STAT) and U6-99 (OPTN ACTIVE STAT), assist the user in
network troubleshooting.
• U6-98 displays the first declared fault since the last fault reset or power cycle.
• U6-99 displays the present DeviceNet Option SI-N3 status.
These parameters are accessible from the DeviceNet network the or the drive digital operator. A drive fault reset or
power off clears and refreshes both U6-98 and U6-99.
Note: In the event of a PLC idle state, the action taken by the DeviceNet Option SI-N3 depends upon the value of parameter F6-54
(Idle Mode Fault Detection).
‹ Automatic Device Replacement (ADR)
This DeviceNet Interface is compatible with the ADR feature associated with Rockwell controllers and DeviceNet
Scanners. ADR features Configuration Recovery and Auto Address Recovery.
„ Configuration Recovery (CR)
CR is the ability of the scanner to download previously uploaded and saved configuration data to the DeviceNet node.
When a DeviceNet node is removed and returned to the network or replaced with another device, an ADR-enabled
scanner reads the Electronic Key of the device that is configured in the scanner. A typical setup of the Electronic Key is:
Vendor ID, Product Code, Model Number and Product Revision. When the CR feature is enabled, the stored
configuration is downloaded to the DeviceNet node.
