Possible Cause An EGD exchange timeout occurred on the requesting controller. Redundant processor (if applicable)
unable to receive UDH EGD inputs and has requested that EGD data be transferred over the IONet.
Solution
• Check UDH network and verify that all redundant controllers are receiving all expected EGD exchanges.
• Verify that all relevant devices are powered on and producing data on the network.

Description Communication lost from R processor
Possible Cause
• IONet or hardware malfunction
• S or T processor in redundant system lost communication with R processor
• Missing cable from the controller to the Unit Data Highway (UDH) network switch
Solution
• Go online with the R processor. Verify that the processor is in the Controlling state. If not communicating or in
Controlling state, restart the processor.
• Check for disconnected IONet cables or malfunctioning switches.
• Rebuild and download the application.
• Check for a defective Ethernet cable to network switch.
• Check for a defective network switch:
− Place the Ethernet cable into empty port.
− If the problem persists, replace the network switch.
