Addressing the IP 265
The IP 265 can be used in slots 0 to 7 of the S5-100U. For each slot, there are eight bytes reserved
in the process image of the outputs (PIQ) and eight bytes in the process image of the inputs (PII).
Data is interchanged between the CPU and the IP 265 via all eight bytes of the PII and the PIQ.

The permissible address range is 64 to 127. The IP 265 is referenced with bytewise or wordwise
load and transfer operations, in the same way as analog input modules or analog output modules.

The IP 265 exchanges data with the CPU of the programmable controller over the S5-100 bus.
The addresses under which you must reference the PII or PIQ depend on the slot into which you
have plugged your module. For this reason, only the address offset for the start address of the slot
in each case has been given in the following explanation of the individual bytes.
Example:
You have plugged your IP 265 into slot 2 of the programmable controller. The start
address is 80.
"Byte 6" in the following refers to the offset of address 80. You therefore reference
byte (80 + 6). The load and transfer operations programmed by you must therefore
refer to byte 86.
