The state of a peer cop health bit reflects the current communication status of its associated node:

A health bit is set when data is successfully exchanged with its corresponding node.

A health bit is cleared when no communication has occurred with the corresponding node within the configured peer cop health time-out period.

All health bits are cleared at PLC start time. The health bit for a given node is

zalways zero when its associated peer cop entry is null. All global health bits are always reported as zero.
