Blog: Build your own Hangglider and Paraglider Winch
Remote control
With a VPN router you are able to connect to the PLC via the mobile net.
It cost around 100 euro and with openVPN you can connect up to 3 devices, typically: the PLC, a tablet as remote control and PC for remote trouble shooting/tracing and PLC update.
PLC settings
Here is a link about the basic settings in the PLC:
HMI Droid
Machine Expert has a built-in HMI interface called WebVisu. It is easy to set up and has a nice design, but it does not include a lifebit functionality, and the entire design is transmitted, which makes data efficiency very low.
In contrast, HMI Droid has a built-in lifebit, and the design is stored locally in the app on the tablet/phone, so only the variables needs to be transmitted over the mobile network.
HMI Droid is a bit older and more rough in terms of how the interface must be designed, but once the design is completed, it works very well.
See the latest version of our HMI Droid screen here:

Just download the app and import the files.
Data plan
With HMI Droid, you only need a data plan of around 5 GB if it runs 24/7.
However, you will probably only use it while flying, so in practice 1 GB or less is likely sufficient.
