3. Technology modules
4. Digital modules
1) Depending on the setting, this address range can also be occupied by status bits (
and Tab. 1/2).

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 bus node counts as a module with 0 inputs and 0 out-
puts when the status bits and the I/O diagnostic interface
are deactivated.
– The I/Os of different module types are assigned separ-
ately from each other.
The sequence in the following table applies:
Description
1)
Can be activated by DIL switch. If the interface is activated, it
will occupy the first 16 inputs and outputs in the address
range.
Modules with analogue inputs/outputs
e.g. CP interface, Front End Controller CPX-FEC
Modules with digital inputs/outputs
