Address assignment

The system CPX-E is composed of a different number of inputs and outputs, depending on the number and type
of modules CPX-E used and the parameterisation of the bus module. The inputs and outputs are assigned
automatically within the system CPX-E.
The address assignment (number of allocated inputs and outputs) on the system CPX-E must be determined prior
to commissioning.
– A maximum of 10 I/O modules + bus module is permitted in one system CPX-E.
– The address space of a system CPX-E is limited. The bus module provides the system CPX-E with
a maximum address space of 64 bytes for inputs and 64 bytes for outputs.
– Activated diagnostic functions as well as status bits or the I/O diagnostic interface reduce the size
of the available address space.
