[Next] [Previous] [Up] [Top] [Contents] [Index] Chapter 9 DM: Run-time Operation 1. Overview of the Display ManagerDM is a real-time tool used to control and monitor the process variables of EPICS systems. It is the counterpart to EDD, which is used to configure the displays for DM. DM was designed to conform to all the EPICS standards. It uses the standard EPICS hardware and software components and runs on the standard EPICS platform.
Displays provide DM's graphical interface. A display is configured using EDD and then stored in a display list file. Display list files often have the extension .
A display contains a number of objects that control or monitor process variables. Objects can be static or dynamic. Dynamic objects are configured in EDD to connect to channels when opened by DM. Such objects do the actual controlling and monitoring of process variables in DM. The term channel refers to a field in an EPICS record (though only the record need be specified, in which case the VAL field is implied). DM connects to channels using Channel Access client requests. To run DM, you must have a basic familiarity with the X Windows interface.
