PVs should only be updated if value would change #254

Closed MichaelWedel closed 7 years ago

MichaelWedel commented 7 years ago

The EpicsAdapter currently updates PVs periodically, in a specified poll interval. The update should only be performed if the value actually changed, which would also provide more useful log messages regarding these updates.

pcaspy already makes sure that value updates are only propagated if the value actually changes, so that is not even a problem - but the log messages still are and doing the check beforehand does not hurt.
