Experimental Physics and
Industrial Control System

Hi,

 

At PSI we do have a running alarm handler with web interface since a couple of years. It's mainly used for the experimental stations as they don't want to keep open all the time a window to be able to keep tracks of the alarms.

 

 

It is written in C# / ASP.NET, runs on a windows server (in a cluster), and uses a MS SQL server as backend. Configuration is done via the web interface and is stored on the DB.

 

However we are currently working on a newer version of the software which uses new technologies like websockets (in the form of SignalR) and a more robust implementation.

 

We can share the code with you however we didn’t released it as open source as we don’t really have the time to support it for 3^rd party institutes. So if you want it just let us know and we shall provide you with all the sources.

 

Sincerely,

 

Alain Bertrand

Subject: EPICS Alarm system via web browser

 

Does anybody have a recommendation on an EPICS Alarm system that you can view via web browser somehow? 

 

At STAR/BNL, we have been using ALH for a number of years.  One of the member of the collaboration would like to be able to see alarm systems via web browser. Ideally, what he can see remotely is the same as what the shift crew can see in the control room, but not necessary to be able to control remotely via web. 

 

Other options for alarms are to write a soft IOC specifically for this, CSS BEAST, Nagios Alarm Handler, CA Watcher, and CSS Alarm System (DESY).  However, as far as I can tell, none of them appears to be able to publish the EPICS alarm info on the web, unless I'm missing something.  I guess Nagios Alarm Handler can work for this, but is there any other options out there?
