5.3.1 Generating a hardware configuration for PROFIBUS in the SIMATIC Manager
Description
The following example of an ET 200pro FC frequency converter with an "IM 154-2 DP HF"
interface module will be used to demonstrate how to generate a PROFIBUS configuration
with HW Config in the SIMATIC Manager. This will take place in three steps:
Parameterizing the PROFIBUS DP interface in SIMATIC S7
Equipping the ET 200pro station
Settings for the frequency converter
Note
For information regarding the interface modules, please refer to the manual "ET 200pro
Distributed I/O System", chapter "Interface modules".
Parameterizing the PROFIBUS DP interface in SIMATIC S7
The PROFIBUS DP interface is parameterized when configuring the hardware. When a CPU
with integrated DP interface or a DP communication processor is selected from the hardware
