Table for calculating the inputs/outputs of type 03
INPUTS
1. Number of 4-input modules ______
⋅ 4
2. Number of 8-input modules ______
⋅ 8
3. The 4 status bits are assigned internally
automatically by the terminal. They must be treated
like inputs and must be added to the intermediate sum:
+
+
Total sum of inputs
OUTPUTS
4. Number of S-type sub-base modules (type 03) ______
⋅ 2
5. Number of D-type sub-base modules (type 03) ______
⋅ 4
+
Intermediate total of 4. + 5.
6. Check whether the sum of 4. + 5. can
be divided by 4 without remainder.
This check is necessary because of
the 4-bit orientated internal
addressing of the terminal.
Different cases:
a) If divisible by 4 without remainder:
continue with 7.
b) If not, round up (+ 2 outputs)
7. Number of electronic output modules ______
⋅ 4
=
+
+
Total sum of outputs
