Possible Configurations
This chapter gives you an overview of possible configurations. The restrictions per-
taining to the number of modules within a configuration are described in a separate
section.
Setup guidelines for PROFIBUS networks
The setup guidelines and information in the manual for SIMATIC NET PROFIBUS
NETWORKS (order no. 6GK1970-5CA20-0AA0) always apply to the setup of a
PROFIBUS network with ET 200R.
In addition the following notes must be adhered to.
Terminating resistance
Terminating resistance must be provided on the first and the last station of a
PROFIBUS-DP network with copper conductors (see chapter 3.3).
Due to the implemented repeater function this terminating resistance is perma-
nently integrated on the ET 200R for every bus segment. This means that when the
ET 200R is used as the last module of the PROFIBUS segment, no external termi-
nating resistance is required.

Electronics/Encoders and PROFIBUS-DP
Connection
With the ET 200R all power and signal lines are installed in one cable and connec-
ted to plug connector X01.
The second plug connector (X02) is used for looping through connections.
The pins of X01 and X02 can carry a maximum current of 9 A.
