Description
Device is not online:
— Device has not completed dup_MAC-id test.
— Device not powered – check module status indicator.
Device is online but has no connections in the established state.
Device is online and has connections in the established state.
One or more I/O connections are in timed-out state.
Critical link failure — failed communication device. Device detected error that prevents it from communicating on the
network.
Communication faulted device – the device has detected a network access error and is in communication faulted
state. Device has received and accepted an Identity Communication Faulted Request – long protocol message.
Module in CAL mode.
Channel being calibrated.
Normal (channel scanning inputs).
Channel at end of range (0 mA or 21 mA).
No power or major channel fault.
