Dear all
We have an odd behavior here with a continuously-running MEDM display.
In most cases, where the EPICS IOC is running in C or similar, the MEDM displays of string variables happily update when the underlying PV is updated.
However, we have a simple EPICS database that is done with PCASpy. We then use a pyEpics client to regularly update records in the EPICS database using pvPut().
The updated numeric records all work fine. However, the string records (when updated) appear as 00.00 or similar in the MEDM display.
If we open a new MEDM display, the correct value is shown. If we slightly resize the MEDM display, it also updates.
Any idea what is going on?
Is there something in the PCASpy database record fields we need to set to make this work?
- Using command-line caput() we get updated values.
— I was going to try an MEDM->caQtDM conversion to see if we get any different behavior.
Thanks
Keith Thorne
