Subject: EDM Horizontal Bar

I am trying to implement a "progress indicator", which consists of a few epics records and two edm widgets.  On the EDM side I have a text control, which is used to set a number of seconds that will be counted down to 0 and which is stored in a longout record.  Another widget is a horizontal bar which shows progress by displaying number of seconds that have elapsed so far.  The horizontal bar connects to a calc record which counts seconds elapsed.  When the longout record, which stores the number of seconds, is processed it also causes the HOPR field in the calc record to be set to the number of seconds.  If the horizontal bar widget connects to the calc record after the number of seconds are set, all works well.  However, if a new value of seconds is entered, new value of HOPR is set and horizontal bar no longer works correctly, since it is still using the old value of HOPR for scaling.

Is there a way to force the horizontal bar to get new PV parameters without switching the edm screen from execute to edit to execute?

Thanks in advance,
Zen
