Process Image for Register Communication
If bit 2^7 of control byte C0 is set to the value 1, the I/O module responds by
setting bit 2^7 of status byte S0 to the value 1.
The process image takes on a different meaning. Instead of process data, it now
contains register communication data. The register communication protocol uses
bytes 0, 1 and 2 of the process image. All other bytes are not valid in this state.
