Hi,

I'm having problems with the meter widget, specifically with the 'Limits

from PV' property. Although the lower and upper range limits are loaded

correctly according to the database record the HIGH, LOW, HIHI and LOLO

values are not loaded at all.

The 'Show PV Info' action available in runtime mode displays NaN for

alarm_low, warn_low, alarm_high and warn_high.

Any ideas what could be the cause of this behaviour?

Cheers,
Pawel Predki
