A Logic output signal from a RMH760B (device 1) wants to be available as a release
command for a second device. A release command generated in device 1 is sent as
transmission object via a digital output. Device 2 uses this command to start a
decentralized aggregarte.
In the reverse direction, any operating message in device 2 is sent as a
transmission object via a digital output to device 1, where it is processes accordingly.
The following send and receive zone is configured for the example 2:
RMH760B, device 1
