Heartbeat monitoring
The number of heartbeats to be monitored can be set via the controller with the corresponding
master node ID and corresponding timeout. If the device does not detect a heartbeat within the
specified timeout period (e.g. in the event of a communication interruption), the device switches
to the
Stopped state and the outputs are de-energized.
