Configuration of the ET 200SP
See the STEP 7 online help or the documentation of the configuration software
manufacturer.
Note
For I/O modules that are installed on a BaseUnit BU..D (light-colored BaseUnit), you always
have to set the parameter "Potential group" to "Enable new potential group". If you do not set
this parameter correctly, the CPU/interface module goes to STOP and generates a
parameter error.
Note
For PROFIBUS with configuration via GSD file
In the configuration software, you must set for the BU covers whether these are on a light-
colored or dark-colored BaseUnit.
