Cyclic Control Word between Master and MOBY-ASM
The cyclic control word is used to synchronize telegram communication between master (FB
/ FC) and slave (MOBY-ASM). The actual non-cyclic command and acknowledgment frames
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.
