1.
Start STEP 7 (TIA Portal) and open the
“MBS_KNX” STEP 7 project from the
“109740160_KNX_S7_PROJ_Vxx.zip” file.
Note
The gateway’s GSD file is installed
automatically.
Requirement: You have STEP 7 (TIA Portal)
V14 or higher installed on your computer.
2.
Open “Devices & networks”.
-
3.
Right-click the connection and select
“Assign device name”.
4.
Assign the PROFINET device name to the
S7-1200 CPU and the gateway.
1. Select the device name you want to
assign.
2. Click “Update List”. The suitable device
type is automatically found in the network
and displayed in the list.
3. From the list, select the device to which
you want to assign the selected name.
4. Click “Assign name”.
