Kay, Thanks for those tips. My database file has LOPR/HOPR as -140/160, but after the IOC is running the LOPR/HOPR are written with new values, e.g. -100/500.
When I use the caget command, the display limits show -100/500. When I probe the tank widget (PV) in phoebus it shows, in the metadata section, display range of -140/160, and when I look carefully on the tank widget scale it also shows -140/160 range for the case where I checkbox to use the PV Limits - so the PV Limits checkbox is working, but ....
How in the heck does phoebus know what the loaded database limits were, rather than reading the PV's current values? Is there a cache where it is read by phoebus one time or upon initial connection? I tried restarting phoebus but it always thinks the display limits are the loaded database's -140/160.
Regards, -ps
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.
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.
