Experimental Physics and
Industrial Control System

Hi ,

Thanks to Matt and Pierrick for sharing the drivers via tarballs. I have tested both drivers with 3.15.3 base, and below is the report. I think both should be exposed to the community: having two is better than none. I can add translated  .opi screens to Pierrick’ version and modifications I made to Matt’s. Please let me know.

I think we are using Matt’s ioc for Lakeshore335 from your personal git space. Please keep in mind, we tested only a small subset of the device functions. 

Building:

• Matt’s:  No Issues. Just for dummies. Make and ready. Removed some SNS specific applications, like slimsam. May be something else.
• Pierrick’s: It was a bit of efforts to build. I had to figure out which libraries and. dbd to include.  Just like any driver from .proto and .db files.  I have created an IOC in my github space with references to where the driver came from.

Database :

• Matt has a lakeshore625_no_magnet.db to be loaded on the top on the lakeshore625.db  if power supply is shorted. We found that we don’t really need it, since the idea was to have a dry run of the real magnet including waiting while ramping.
• Just one database.

Dry Run without magnet connected (terminals are shorted):

I have translated Pierrick’s .edl screens to .opi by autotranslator from SNS CSS. I have modified the shrift on all text widgets to auto, because it was too large as well as  how the new display is being opened. It was stand alone, I changed it to tab. 

• Matt’s: The beamline scientist found appealing the simplicity and limited functionality on the GUI, because of less opportunity to mess up. It was inconvenient not to be able to set the limits, but later we figured out how to do so from a command line via caput. Configuration happens once.
• Pierrick’s:  everyone who came by was appealed by the gauges’ widgets. The beamline scientist liked so many functionalities exposed, especially he found the ramping ranges to be very nice. He was very concerned that the real users will have plenty of opportunities to screw up. I comforted him that GUI can be adjusted to user and expert.

Real Run with the magnet will happen on February 15 with the friendly user. They couldn’t decide which one to pick at the moment and I suggested trying it on a friendly user.
