Introduction Extensible display manager Widget set PV support Web site: ics-web 1. sns. ornl. gov/edm Development history Distribution Documentation
What’s New? Bugs and bug fixes Small changes and behavior tweaks View macro and environment values X/Y graph option to auto-scale inward Ramp widget
What’s New? Make related changes by Janet Anderson Possible problems with Solaris May have to delete …extensions/include/edm/* when updating Qt version will eventually be available Port became stalled due to poor text performance Latest version is better
Features Widgets Monitor Graphic Control Simple dynamic behavior Color and visibility may depend on PV value Simple symbol facility Build display symbols composed of graphic widgets Display state (64) may depend on values of multiple PVs Simple layout management aids Align, center, distribute, size, group, fine position adjust via keyboard
Features (cont) EPICS, local, calc pvs LOClocpv 2=e: 1, zero, one, two LOClocpv 1=d: 0 CALC{A=5? 0: B/(A-5)}(pv 1, pv 2) Functional colors and color rules Inferior to edd/dm
Features (cont) For edl generating tools… edl file may contain arbitrary embedded metadata meaningful to external tool Run-time configuration option generates file display list syntax Input filter mechanism Employs external script or executable to transform contents of a foreign file based on file extension medm adl file (adl 2 edl) EPICS ascii db file (in-house perl script)
Features (cont) Remote file access via curl Utilizes Xlib, Xtoolkit, and motif Remote access via ca gateway and webserver One process can manage multiple screens on multiple remote displays Installation/configuration can be difficult
