Indicator Status for Modules
Status Description
Module status Off No power applied to device.
Green Device operating normally.
Flashing green Device needs commissioning due to missing, incomplete, or
incorrect configuration.
Flashing red Recoverable fault.
Red Unrecoverable fault occurred. Self-test failure present
(checksum failure, or ramtest failure at cycle power).
Firmware fatal error present.
Flashing red/green Device is self-testing.
Network status Off Device is not online:
- Device has not completed dup_MAC-id test.
- Device not powered – check module status indicator.
Flashing green Device is online but has no connections in the established
state.
Green Device is online and has connections in the established
state.
Flashing red One or more I/O connections are in timed-out state.
Red Critical link failure – failed communication device. Device
detected error that prevents it from communicating on the
network.
