What it is and which purpose it serves
What it is
This is a demo aggregation site, or a portal, gathering several demos from multiple target machines.
An "Ada for Automation" based application can be built with a Web User Interface (WUI) and allows to monitor and control its operative part.
Here you can get an idea of what is possible to achieve with this framework.
How it works
Somewhere in the cloud there is a virtual machine running a Debian distribution.
The Apache web server can be configured to proxy many virtual hosts, each connected to an application.
Some of the example applications are running on the same virtual machine, some are running on other target machines connected to real operative part using industrial communication protocols by means of Hilscher products.
Again, no mystery, Stéphane is an Hilscher France technical support guy!
The Gnoga FAQ explains how to configure the Apache web server to proxy virtual hosts.
It also explains how to use HTTPS and this will be the next step!
Basic example with Modbus TCP communication
