7.15 Object 1017h: Producer heartbeat time
The producer heartbeat time indicates the configured cycle time of the heartbeat in
[ms]. The value 0 disables the producer heartbeat.
If the heartbeat producer time (value > 0) is configured the heartbeat protocol, cyclic
sending of heartbeat messages, begins immediately.
If the heartbeat producer time was configured the heartbeat protocol starts on the
transition from the NMT state INITIALIZATION to the NMT state PRE-OPERATIONAL.
In this case the boot-up message is regarded as first heartbeat message.

It is not allowed to use both error control mechanisms “Guarding protocol” and
“Heartbeat protocol” on one NMT slave at the same time. Thus, if the heartbeat
producer time is unequal 0 the heartbeat protocol is used.
