Hi,
I heard that there is an option of using mqtt on andriod. With that you could connect to your MQTT broker for the unser interface. Another option would be that you use 1.9.0.M1 where a first version of OPC UA integration is available. I know people using UPC UA clients in NodeJS and then building a web app for the ui.
hope this helps.
Alois

Hi,
first of all you need to make sure that the PLC controlling your system is supported by Forte.
A good idea about 4DIAC is to show that the same application can be used even if the Hardware changes, using the virtual DNS. You could show the system beeing monitored and controlled by you App using the PLC, and then change it for another PLC or a raspberry PI and show that nothing has changed in the APP.
If you want to go further, you can send the information from the PLC a self managed cloud, so you could show the same information not only in your android phone but also in a webpage or in a iphone app. This will allow to easily expand the system like to handle security in a better way, sending notification emails, and why not, real-time video (not with 4DIAC, but if you use a raspberry PI, I know you can easily connect a camera).
Once you have your data on the Internet, possibilities are endless.
Jose

Thank you for your replies, I appreciate. My question was more like: What interesting things I can do with the PLCs running FORTE on them? What could be some interesting applications?
What's the role of Virtual DNS ? What it does precisely ?

This depends a little bit on the equipment you like to control and the sensors and actuators it offers. For example if the belt you mentioned has a position sensor for the wagons you could do a closed loop position control. So you could have a position setpoint you enter in the mobile HMI and the controller moves the wagon there. And once that is done you could also think about path control i.e., you give a position profile which the wagon should follow. With that you can for example make smooth starts and stops.
Virtual DNS is in principle a simple key value store. When configuring distributed applications you often need on two or more places the same configuration parameter. With virtual dns you can centrally manage a configuration parameter value and give it a symbolic name. On download the symbolic name is then replaced by the real parameter. This is also interesting when you have different setups and depending on the setups you select different virtual dns configurations.
