Which Addresses Are Assigned - Siemens SIMATIC S5 Manual

IP 267
5.2.2

Which Addresses are Assigned?

• The IP 267 assigns addresses in the analog range of the S5-100U. The module
addresses are preset by the fixed slot addressing of the programmable
controller. You can operate the IP 267 in slots 0 to 7 ( Table 5-1.). Eight bytes
are reserved per slot and the first four of these bytes are assigned.

• If you use the IP 267 in slot 3 of the programmable controller, for example,
bytes 88 to 91 in the process output image (PIQ) and the process input image
(PII) are used for communication between the CPU and the IP 267. The other
four bytes remain unused. You can reference these addresses with the STEP 5
load and transfer operations (
messages between the CPU of the programmable controller and the IP 267.
