Hello,
I'm using Epics v3.12. I added scan rates of .05 second (20 Hz), .025
second (40 Hz), and .016667 second (60 Hz) to the list in choiceGbl.ascii.
I rebuilt default.dctsdr and found these three rates added to the file.
The problem is that scanppl informs me that rates of ".025 second" are
running at ".016667 second". A dbgf "record.SCAN" does return the correct
value of ".025 second". A logic analyzer says that the scans are occuring
every 16.7 milliseconds. The scanPeriod task that these records are in has
a priority of 51, the second highest priority.
I did another test where I removed the 60 Hz entry from choiceGbl.ascii and
saw the same thing.
I think the records are being processed by the correct scanPeriod task at
the wrong period.
Any insight is greatly appreciated.
Geoff
