Note
For the digital modules with diagnostics, the diagnostic data is additionally
mapped into the process image. Module 750-506 used as an example here-
above, shows 4 bits in the output process (1 bit output value and 1 bit unused
per channel) and 4 bits in the input process image (2 bits diagnostics per
channel - wire break, short circuit).
