4 Configuration and Project Engineering
This chapter describes the configuration in STEP 7 (TIA Portal) and the
programming of the gateway configuration files.
If you want to use the sample configuration of this application example without any
changes, you can download the STEP 7 project directly to the S7-1200 CPU and
the gateway configuration to the gateway (see Chapter 5.3.1 Commissioning the
gateway).
4.1 STEP 7 (TIA Portal) device configuration
Note
Before you can configure the gateway in STEP 7 (TIA Portal), you must install
the gateway’s GSD file. The GSD file can be found on the gateway’s web user
interface, “Profinet > GSDML file”. \6\ provides a description of how to install a
GSD file in TIA Portal.
When you open the supplied “MBS_KNX” STEP 7 project, the GSD file is
installed automatically, see 5.3.2 Commissioning the S7-1200 CPU.

No.
Action
Comment
1.
Create a STEP 7 (TIA Portal) project and
insert an S7-1200 CPU (S7-1214C DC/DC/DC
FW4.2).
Requirement: You have STEP 7 (TIA Portal)
V14 or higher installed on your computer.
2.
In “Devices & networks”, open the “Network
view”.
In the hardware catalog, navigate to “Head
module”, “UGW-micro”.
Make sure that the firmware version (V2.31) is
correct.
