Save & Restore: incorrect delta between live value and stored set point

[claudio-rosati]

Using a simple integer value as PV value, Save & Restore in CS Studio erroneously shows a non-zero delta value even if stored set point and live set point are equal, or a wrong value. See attached screen shots:

In other cases (e.g. doubles) the delta is displayed correctly.

@georgweiss an I missing something?

No idea about the specifics of the save/restore tool, but your PV is indicated as never processed (UDF_ALARM, zero seconds since epoch for time stamp). So the tool could consider this as PV-has-no-valid-value. Do you still see the error when you process the PV?

I'm not experienced enough in Epics to say for sure, but attached screen shot indicates that the PV does indeed have a value.
