6.3.1.6 Inserting the inverter into the STEP 7 project
● Install the GSD of the inverter in STEP 7 via HW Config (Menu "Options - Install GSD
files").
Once the GSD has been installed, the inverter appears as "SINAMICS G120 CU240x-2
DP V4.3" object under "PROFIBUS DP - Additional field devices" in the hardware catalog
of HW Config.
● Drag and drop the inverter into the PROFIBUS network. Enter the PROFIBUS address
set at the inverter in HW Config.
● Insert the required telegram type from the HW Catalog to slot 1 of the inverter by
'dragging and dropping'.
STEP 7 automatically allocates the address range in which the inverter process data are
located.
The inverter object in the HW Config product catalog contains several telegram types. The
telegram type defines which data is exchanged between the control and inverter. More
information on the telegram types can be found in Chapter Cyclic communication
(Page 112).
Information o
n connecting the inverter via PROFIsafe can be found in the Safety Integrated
Function Manual.
