Hi,

If I've understood this correctly, there are 2 ways you can do this:

1) Use (560) menu muxes on the top level screen. Point each menu mux to
the PV that provides $(MODE) as an integer value, and get it to populate
a macro that is used to launch the correct related display for that
trigger

2) Make a pdu_trig_generic.edl display with contains only an embedded
window, and get all the related displays to launch this. Make this
embedded window use a menu source, and point the PV to an mbbo that has
$(MODE) as its value for that trigger. You can then fill in the 4
entries in the embedded window with edm screens for your 4 modes

Personally I'd choose option 2.

Thanks,
