NET station heartbeat
In order to make it possible for all NET stations within a group to be able to know
whether NET stations important to them are still communicating, each station cyc-
lically sends a heartbeat every second (1 s).
If a heartbeat is not received, the corresponding error bit ID01 – 08 will be set to "1"
until a heartbeat is detected.
