3.11 Producers heartbeat
The heartbeat protocol provides additional monitoring of the CAN bus without knowledge of
the heartbeat producer via the connected user.
A heartbeat producer sends cyclically a heartbeat message. The time when the message is
sent, is adjustable. The heartbeat protocol starts as soon as the heartbeat producer time is
set. If the heartbeat protocol already has a value unequal 0 (at unit switch on) the protocol
starts during transition from initialization to pre-operational. In this case, the bootup message
is considered before the heartbeat message.
3.12 Consumers heartbeat

this time, an adjustable behavior is started. The consumers heartbeat protocol starts with the
rstheartbeatsignal.
Attention
It is not possible to activate the guarding protocol and the heartbeat
protocol simultaneously on one unit. The guarding protocol only
works when the consumers heartbeat time is 0.
