Fig. 1/5: Address assignment of a CP system, example
Festo P.BE−CPX−CP−E N en 0405NH
PROFIBUS addresses are used starting at input/output
word 45. The CPX−CP interface thus occupies 12 byte input
addresses and 16 byte output addresses.

The address assigment (method of counting, order of the
I/Os) within the individual CP valve terminals and CP modules
can be found in the appropritate manual for the module.
You will find an overview of the address assignments of typi
cal CP modules in the appendix, section A.4.
