Cyclic Control Word between Master and MOBY-ASM
The cyclic control word is used to synchronize telegram communication between
master (FC) and slave (MOBY-ASM). The actual non-cyclic command and
acknowledgment telegrams via DP/V1 may not be started until this is indicated by the
cyclic byte of the MOBY-ASM in the command or acknowledgment counter.

Command counter, higher bit (BH)
Startup message
This bit shows that the MOBYĆASM has performed a
startup (ANZ_reset_).
After reset of init_run_, the MOBYĆASM resets this bit.
Commands other than a RESET or faulty RESET
command are then rejected with an error message.
init_run_
Startup of the PROFIBUSĆDP master
This bit forces the MOBYĆASM to start up.
Bit 15 is then set on the I/O output.
