Addressing in the IP 265 User Program (IP 265 Viewpoint)

All interfaces of the IP 265 are addressed in the IP 265 user program with fixed actual addresses:
• 24 V inputs and 24 V outputs
• 5 V differential inputs
• Expansion inputs/outputs
• Parameter interface
5.1.1 Actual Addresses of the Inputs and Outputs of the IP 265
Note
The actual addresses of the inputs and outputs of the IP 265 are slot-independent in the
IP 265 user program.
Table 5-1. Addresses of the Inputs and Outputs of the IP 265
Inputs/Outputs
24 V inputs
24 V outputs
Differential inputs
Expansion inputs
Expansion outputs
* can only be used alternatively
The differential inputs and the expansion inputs/outputs are connected to the same 15-pole sub D
socket. The differential inputs and the expansion interface cannot be used simultaneously.
You may use each of the 8 pins of the expansion interface either as expansion input or as expansion
output (configurable with COM 265).
Note
The inputs and outputs of the IP 265 are local and therefore not directly accessible via
the normal address space of the CPU. Their allocated fixed addresses do not appear in
the CPU user program.
