Restriction Of The Modules Which Can Be Connected - Siemens SIMATIC ET 200R Manual

Possible Configurations
Feeding in and looping through with one cable:
The power for the electronics, encoder and load are fed together with the
PROFIBUS-DP and other signal lines in one cable to the first ET 200R and then
connected through to the ET 200Rs behind.

Restriction of the modules which can be connected

Current consumption
The maximum configuration depends on the current consumption of the individual
modules. For more information see the technical data (chapter 7).
Setting the address
The number of modules is limited by the number of addresses which can be set
(1 to 99).
Number of repeaters
Due to the permanently integrated repeater the number of ET 200R devices which
can be installed in one PROFIBUS branch is limited to nine.
