Inputs
1. Number of 4−input modules ________ x 4
2. Number of 8−input modules ________ x 8
3. Number of 16−input modules ________ x 16
4. Number of other inputs, e.g. multi I/O module
5. The 4 status bits are assigned internally automatically by the valve terminal.

Intermediate sum 6.9.
10.Check to see if the sum of 6. 9.
is divisible by four without remainder.
This check is necessary because of the 4−bit−orientated
internal addressing of the terminal.
The following distinction is made:
a) if divisible by four without remainder: continue with point 11.
b) If not: round up to the next half byte (+1...3).
