[Halld-controls] [Dsg-halld_plc] PVs to be added to IOC for display in WEDM

[Hovanes Egiyan]

Hi,


There are multiple ways to deal with these, but I think the most 
efficient would be to make some changes

to the source where these variables come from.


Nick, can we add another status tag similar to MPS_Status_Read, but 
instead of DINT array use BOOL array type?

Then I can transfer it into EPICS as mbbiDirect records, and Tyler can 
use those two to display in the EDM GUI.

I do not know why would this array be DINT in the first place.


The numbers shown on the solenoid voltage screen mostly come from PXI, 
so the summing should

probably be done on PXI, which means Brian could check if he can create 
four more variables

to provide the summed voltages.


FDC:CHILL:STATUS and FDC:CHILL:ALARM1 EPICS records are mbbiDirect type 
records, byte monitor

should be able to show them properly.


Hovanes.
