Craig has written a python script to launch ndscope from MEDM via the 'Execute' pull-down menu (see attached image). After selecting the PV you wish to plot, ndscope is launched with this EPICS PV name as its data channel.
Please note not all filter module EPICS channels are acquired by the DAQ, specifically the switch settings (SW1,SW2) and the output monitor channel (OUTMON). If you select these PVs the ndscope screen with show a red banner at the bottom with an 'Invalid channel name' error.
If you find a non-frontend MEDM PV which is not in the DAQ but should be, please contact me and I'll add it to the appropriate EDCU ini file.
On a slightly related topic, for fun I ran ndscope on a four 4k-monitor Zotac machine, showing corner station PEM seismometer data (X,Y and Z channels) at full data rate with a 400 second look-back. The plot scrolled smoothly across the screens with not a glitch.
