The Gorilla app is a human-machine-interface (HMI) to a Siemens Simatic S7 plc. The app offers a very simple user interface, which can easily and flexibly operate on complex controls.

All relevant control functions are possible:

- HMI (HMI / SCADA)
- Menu Control
- Features on / off - enable / disable
- Changing parameters
- Display of process data

The Gorilla app is the active communication part, but the optics, the behavior and the possible functions and data, however, will be determined by the plc. The communication with the controller is implemented by using the TCP/IP interface and works via Wi-Fi or 3G.

The connection parameters will be realized by scanning a "Gorilla code". Within this code all the necessary parameters like IP address, etc. are included. Thus, the Gorilla app is prepared and ready to communicate with the plc. Further settings to the Gorilla app are not necessary.

The interface between the Gorilla app and the controller (plc) has to be configured to the requirements and possibilities of the interface definition. How this interface definition is realized and all further information concerning the Gorilla app in detail, please visit our website at https://www.pias.de/gorilla (See Support link URL)
A full description of the interface definition will be available approximately in the middle of august.

To check out how the Gorilla app works, you can go to our website http://plc.pias-online.de. There you can see a reflection of the Gorilla app. When you start the app, it will instantly connect to our test plc. When you press the buttons you will feel the iPhone vibrate, which is a force feedback from the plc. Also you should see on the website which button you pressed. Be sure to hold the button pressed long enough, because the update of the website isn't as fast as the communication to the plc.
