4.6 Alarm Codes, Descriptions, and Suggested Actions
Description
This flag is set when an uninitialized card
is detected on the bus after the init se‐
quence is complete. The most com‐
mon cause of this condition is a Node/SN
list that does not precisely match the card
mix on the bus either due to missing en‐
tries or typographical errors.
CAN card I/O malfunction that causes in‐
itialization failure, loss of heartbeat re‐
sponses from a CAN card or loss of com‐
munication with one or more channels of
the node.
