2.1.2 Address assignment of the CPX terminal

2-10
Note
If necessary, status bits or an I/O diagnostic interface can
be activated by DIL switch (see Tab. 1/2):
– If the 8 status bits are activated, they will occupy the
first 16 inputs in the address range (8 used).
– If the I/O diagnostic interface is activated, it will occupy
the first 16 inputs and outputs in the address range.
If you configure the CPX terminal with an EDS file,
the field bus node must be installed in the first location as
module 0.
Basic rules for addressing
– The address assignment of the inputs does not depend on
the address assignment of the outputs.
– Counting from left to right, addressing bytewise:
Modules with less than 8 bits occupy an 8-bit address
space, but do not use it completely.
– The fieldbus node counts as a module with 0 inputs and 0
outputs if the status bits and the I/O diagnostic interface
are deactivated.
– The I/Os of different module types are assigned
separately from each other.
The sequence in the following table applies:
