Configuration Of The Et 200X Distributed I/O Device (Example) - Siemens SIMATIC ET 200X Manual

Product Overview
Basic and expansion modules
An ET 200X distributed I/O device consists of a basic module in which some digital
inputs and outputs have already been integrated. Up to 7 expansion modules can
be added to the basic module.
An ET 200X distributed I/O device is connected to PROFIBUS-DP by means of
cable connectors for PROFIBUS-DP on the basic module. Every ET 200X
distributed I/O device is a DP slave on PROFIBUS-DP.
ET 200X with BM 147/CPU can also be configured for standalone operation (i.e.
not connected to a bus).
