2.1.2 Address assignment of the CPX terminal
Pl ease n o te
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
f i r st location as
module0.
Basic rules for addressing
The address assignment of the inputs does not depend on
the address assignment of the outputs.
Counting is from left to right, addressing in by tes :
Modules with less than 8 bits occupy 8 bits address
space, but do not use all this space.
The field bus node counts as a module with 0inputs and
0 outputs when 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 then applies:
