+The TIA Portal project consists of a CPU 1517V-1 PN, a T900 Comfort panel and a SIMATIC PC station, more precisely the WinCC Unified Edge RT.

+### Operation via Edge Device (extern)
+
+To visualize the TIA project on an Edge Device, the WinCC Unified Runtime must be installed on the device. The app can be adquired on the Industrial Edge Hub to download it to your IEM
+
+![](graphics/WinCC_app.png)
+
+In order to visualize the project on the Runtime, the Ethernet address on the SIMATIC PC station must be the Edge Device's IP address. This can be changed under Device configuration of the SIMATIC PC station, under PRofinet interface>Ethernet address

+
+Once the app is downloaded to the device and the program has been complied and downloaded both on the vPLC and the WinCC Unified Edge RT, the Runtime Manager can be used to visualize the project. When openig the app, it open the user login page. The credential from the created user are Username:edge, Password:Tank4Edge!

 ### Operation via Edge Apps (extern)
 
 The tank application can be controlled via self developed Edge apps. Therefore the following parameters must be triggered (see dedicated explanations):
