Table for calculating the inputs/outputs (type 03)
INPUTS
1. Number of 4-input modules _______
⋅ 4
2. Number of 8-input modules _______
⋅ 8
3. The 4 status bits are assigned automatically by the terminal
internally. They must be treated like inputs and must be
added to the intermediate sum
+
Total sum of inputs to be configured
OUTPUTS
4. Number of S sub-bases (type 03) _______
⋅ 2
5. Number of D sub-bases (type 03) _______
⋅ 4
+
Intermediate sum of 4. + 5.
6. Check that the sum of 4. + 5. is divisible
by 4 without remainder. This is necessary
because of the 4-bit orientated internal
addressing of the terminal. A distinction must
be made between the following cases:
a) If divisible by 4 without remainder then continue with 7
b) If this is not the case, round up (+2 O)
7. Number of electronic 4-output modules ______
⋅ 4
Total sum of outputs to be configured
Σ I
Σ O
