Hi Beni,

You are correct, I just forgot to change the label after copying the label. It's been corrected.

Thanks,
Tyler

Hi Tyler,
that looks great!
Note that under "Beamline Devices" on the far right side just before the TAC that device is most
likely the "Compton Calorimeter" not a "Collimator" as indicated.

Hovanes, correct me if I am wrong.

cheers,
Beni

Hi Hovanes,

I've finished a first version of the GlueX Overview WEDM screen (link below).

https://epicsweb.jlab.org/wedm/screen?edl=%2fcs%2fopshome%2fedm%2fdsg%2fhall_d%2foverview%2fgluex.edl

Most of the indicators are on the screen, but I have a few questions/comments on the screen:

  1.  There were a few places under the bottom "Rates" section that I'm guessing used the Greek letter for gamma. I'm not sure if WEDM can do those special characters so I just put the word "gamma" where the symbol is.
  2.  Under the "Beamline Devices" section, there are a lot of indicators for the status of positions of devices. In CSS, the indicators show UNDEFINED if the product of all the PVs in the rule is zero. I'm guessing that these PVs are Boolean indicators for limit/location switch positions? If that is correct, should these indicators show UNDEFINED if all of those PVs are false, indicating that no switches have been tripped for the device location?
  3.  WEDM doesn't have an equivalent of the plots in the "Rates" section, so I just left those out. If it'd be better, I can figure out an image or graphic to act as a placeholder so there isn't as much empty space.

Thanks,

Tyler
