Re: [EXTERNAL] phoebus Tank widget: Limits from PV?

["Kasemir, Kay via Tech-talk" <tech-talk@aps.anl.gov>]

When I try it with this type of record, tank & meter & progress bar all get the 0..10 range from the record:

 

record(calc, "ramp")

{

   field(SCAN, "1 second")

   field(INPA, "ramp")

   field(CALC, "A<10?A+1:0")

   field(HOPR, "10")

   field(LOPR, "0")

}

 

In “probe” you should also see “Display Range: 0.0 .. 10.0”, and from a command line `caget -d CTRL_DOUBLE ramp` should show the same Lo and Hi disp limit.

Subject: [EXTERNAL] phoebus Tank widget: Limits from PV?

Hello, 

I have used  the checkbox to select "Limits from PV'' which I expected would be taken from  LOPR and HOPR of the PV.  That checkbox seems to make no difference;  the tank's range is always the Minimum and Maximum values used for the widget's properties.  I see the same ignoring of PV limits for the meter and progress bar.

 

I'm using channel access for the PV's ,  and version master 2023-06-28 04:51,  but some earlier versions I have do the same thing.

 

Regards,
