3.2.3 Addressing examples (examples of address assignment)
General example
The following representations show t he address a llocation of the inputs and outputs with enabled
system diagnostics, different mapping optimisation (cycle time optimised or optimised station) and an
identical configuration of the CPX terminal:
16 DI, 24 DO, 10 AI, 8 AO.
Mapping optimisation: optimised cycle time
The following configuration arises from the address capacity of the CPX terminal:
3 Stations, 1-fold cycle time.
