Allocation Of The Parameter Addresses In The Ip 265 User Program; And In The Cpu User Program - Siemens SIMATIC S5 Manual

Addressing
5.3.

Allocation of the Parameter Addresses in the IP 265 User Program

and in the CPU User Program

In order to prevent programming errors, the tables below give you an overview of the correct
addressing of the parameters of the IP 265 (repetition from the preceding sections).
The information given in Tables 5-7 and 5-8
• illustrates the differences in programming of the parameters in the IP 265 user program (IP 265
viewpoint) and in the CPU user program (CPU viewpoint),
• allocates the parameter addresses in the CPU user program to the IP 265 user program
