9.3.10 Heartbeat protocol
The master monitors the state of the actuator via heartbeat protocol. While doing this, the
actuator sends cyclically its NMT status.
The actuator sends the heartbeat telegram independently, without request via RTR frame. The
actuator is a heartbeat producer, it does not receive nor process heartbeat protocols.
