new PEM DAC drive MEDM
On Robert's request, I've created an MEDM which shows a summary of the PEM filter modules which are driving the GDS 18bit DAC outputs. The MEDM shows all three locations (4 DAC channels at each end station, 7 in the corner).
For this application, the state of; no filter control modifications and zero output counts is nominal. Any deviation from this state is flagged RED.
The screen has been linked to the SITEMAP as the last entry in the PEM pulldown.

The 'related display' button on the upper right opens the full FILTER.adl MEDM for the filter module. This small overview is read-only, you need the full screen to make changes.
