Heartbeat producer
The I/O system 1000 transmits a status telegram to the fieldbus and can thus be
monitored by other nodes.
The settings are made in index 0x1017.
 Producer heartbeat is started automatically if a time > 0 is entered in index 0x1017 and
the I/O system 1000 changes to Operational.
 After the cycle time has elapsed, the status telegram is transferred from the I/O
system 1000 to the fieldbus.
 A reset takes place by a change to Operational.
