RE: Browser based EPICS GUI

["Bertrand Alain Gregor" <alain.bertrand@psi.ch>]

Hi,

 

We are currently investigating something in this direction as well, and this is our current status:

 

MEDM screen

 

Web Display

 

On top you see the original MEDM panel, and under the same panel viewed inside a browser (Firefox, but it works with IE and Chrome without troubles as well).

 

The source of our current project can be found here:

http://sourceforge.net/p/epicssharp/code/HEAD/tree/WebDisplay/

 

Currently our tool is able to open ADL (MEDM) and UI (CaQtDm) files, however not all the widgets are yet supported and there should be more time invested to make it fully usable. It’s a read only port which means you will not be able yet to set values via web, however that should not be difficult to implement.

 

It uses a C# / ASP.NET / SignalR backend (websockets for near realtime updates) and an HTML / JS frontend which is compatible with most modern browsers. You can run it even on a tablet or a smartphone.

 

As said at the beginning, this is an early prototype to see if it can be done (which seems to be yes), and how much interest we have here internally for such tool.

 

Sincerely,

 

Alain Bertrand

Hi,

Does anyone know of a project or collaboration to provide web-browser based EPICS control screens? I am trying to get a feeling for how possible it would be to create a framework for this concept.

Thanks!
