[Dsg-rich] IOC for RICH interlock cRIOs

[Tyler Lemon]

Hi Nathan, 

This morning, all of RICH's interlocks EPICS screens that were showing undefined values yesterday are now working. 

Like last week, nothing was done on the cRIO to fix it so the reason it is working again is unknown. 

Best regards, 
Tyler

Tyler, 

You clearly are sucessfully writing some of the PVs on those screens (e.g. all the ones without pink boxes). Maybe you are not trying to write them all? Or are you writing them from different crios, and the UDF ones are only written by a certain crio?

P.S. 
Unrelated, but you could use clonpcrich1 for your gui development instead of clonsl2, since clonpcrich1 is dedicated for rich and clonsl2 is used by lots of people. Although you may want to check with rich group on that.

Can you send me a screenshot of what you’re referring to, while hovering over one of the widgets to show the popup for one of the PVs in question? Or just the result of a caget pvname.STAT. Also, what machine are running your client GUI on?
