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.
Fault Condition
No Fault
CPU Error
PLC in Idle State
Force Fault
Network Power Loss
Connection Time-out
Dup MAC ID
Bus-Off
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.
