Input/output modules and system
1. Number of input modulesCPX-4DE
2. Number of input modules CPX-8DE, -8NDE, -8DE-D + __ x 8 I
3. Number of input modules CPX-16DE
4. Number of output modules CPX-4DA
5. Number of output modules CPX-8DA
6. Number of multi I/O modules CPX-8DE-8DA
I/O
7. Number of inputs and outputs of other modules
(e.g. analogue modules)
8. VTSA... pneumatic interface:
Number of configured valve solenoid coils (+8 O, 16 O, 24 O, 32
O)
32 O are configured at the factory!
7. Inputs and outputs of the modules
Sum of 1 to 6:
8.. Diagnostics if set
Diagnosis M2 and M4
Diagnostics M3
Check whether the greater value (inputs)
from item 8 is divisible by 16 without remainder (diagnostics
begins with the next word):
a) if divisible by 16 without remainder:
b) if the remainder = 12: round up to the next word. + 4 I
c) if the remainder = 8: round up to the next word. + 8 I
d) if the remainder = 4: round up to the next word. + 12 I
9. Inputs and outputs of the modules
Sum of 7 to 8:
Sum total of inputs/outputs to be configured
Greater value (inputs or outputs) from 9:
1)
The maximum number of the available I/Os from Tab. 2/1 must not be exceeded.

Calculating the number of inputs/outputs
Use the following table for calculating the number of inputs
and outputs on your CPX terminal.
