RE: Vacuum GUI: Vac. Status and Pumping Procedural Aid

Hi Daniel,

 

Sorry for the delay in replying.  I don’t know if you’ve received any replies to your post.

 

I have attached screen shots of the Equipment Protection System on our beamlines at the APS.

 

Our vacuum systems are protected by PLCs.  The attached screen shots are from medm.  You will see where requests can be made to open or close gate valves, etc.  The vacuum is displayed in analog readings from the Pirani and cold-cathode gauges, by binary setpoints on the gauges, and by the values read from the ion pumps.

 

These screens also include water-flow, x-ray safety shutters and other non-vacuum related components.

Subject: Vacuum GUI: Vac. Status and Pumping Procedural Aid

 

Hello,

 

I’m curious if anyone has any examples of how their lab implements EPICS based Vacuum Screens. Any and all examples or ideas would be appreciated, but I’m particularly interested in screens detailing sections separated by beamline gate valves. My intent is to develop these screen(s) in cs-studio.

 

Besides controlling and monitoring pumps, valves, and gauges, my target user will:

-likely be doing maintenance or upgrades to a section of beamline (replacing diagnostic drives, a variety of pumps, seals, or hoses; performing leak checks.. etc.).

----likely be focusing on this screen specifically to do the task at hand, conserving screen space isn’t as necessary as when considering controls for typical operations.

-Not always remember all of the underlying PLC logic for interlock conditions. (# of seconds given to perform an action, which valves up or down stream need to be open, etc.)

-Have to decide on an efficient pumping procedure that could vary by section and could also change depending on how the last user left the system.

 

The resulting goal is to have an intuitive screen which additionally serves as a procedural aid.

 

I very much appreciate any and all input.

Thanks!
