ControlNet status interpretation
• steady – indicator is on continuously in the defined state.
• alternating – the two indicators alternate between the two defined states at the same time (applies to
both indicators viewed together). The two indicators are always in opposite states, out of phase.
•
flashing – the indicator alternates between the two defined states (applies to each indicator viewed
independent of the other). If both indicators are flashing, they must flash together, in phase.

node is not configured to go on line make sure the configuration keeper node
is present and working ➀
flashing red/off media fault check media for broken cables, loose
connectors, missing terminators, etc.
no other nodes present on network add other nodes to the network
flashing red/green incorrect network configuration cycle power or reset unit
If fault persists, contact your Rockwell
Automation representative or distributor.
➀ The configuration keeper node is the node responsible for distributing ControlNet configuration data to all nodes on the
