•The device has not completed the self test yet.

•The device may not be powered, look at Module Status Display.

•"ONLINE" = Device is on-line but has no connections in the established state.

•The device has passed the SELF test, is on-line, bus has no established connections to other nodes.

•For a Group 2 Only device it means that this device is not allocated to a master.

•For a UCMM capable device it means that the device has no established connections.

•"CONNECTED" = The device is on-line and has connections in the established state.

•For a Group 2 Only device it means that the device is allocated to a Master.

•For a UCMM capable device it means that the device has one or more established connections.

•"CONN TIMEOUT" = One or more I/O Connections are in the Timed-Out state.

•"COMM FAULT" = Failed communication device. The device has detected an error that has rendered it incapable of communicating on the network (Duplicate MAC ID, or Bus-off).

•"ID COM FLT REQ" = A specific Communication Faulted device. The device has detected a Network Access error and is in the Communication Faulted state. The device has subsequently received and accepted an Identify Communication Faulted Request Long Protocol message.

5.1Checking the Normal Display

Place the selector switch in “LOCAL” or “REMOTE” position. The valve position will be indicated at the top of the LCD. “STATUS OK” or “DNET COMM LOSS” should be indicated at the bottom of the LCD display.

If “STATUS OK” is displayed, the DNFU is communicating with the DeviceNet network.

If “DNET COMM LOSS” is displayed, no communication is occurring. This could be due to a number of factors, including problems with the host DeviceNet system and/or network. Check all local connections and configurations. Confirm that the host is connected, configured for baud rate, protocol to match DeviceNet, and operational. See also Section 7, Troubleshooting.
