Slow Monitoring and Control system (SlowMonCon) - Overview

This page contains background information on the slow monitoring and control system, an overview of the control screen, information on how to log in to the control system screen, and links to more information on individual screens.

For more detailed information, see the Slow Monitoring and Control Operator's Guide.


The Slow Monitoring and Control system is based on EPICS. Displays, archiving, and alarms are provided by Control System Studio. Virtual screens are provided using VNC.

Control System Studio has an extensive users' manual accessible from the "Help" menu within the application. The key parts of it for MicroBooNE have been extracted for browsing at this link.

About Control System Studio and "Perspectives"

Control System Studio (CSS) is based on Eclipse, a development environment for Java. Some tips:

  • Menus and task bars can be hidden using F8 to switch to a screen-efficient "compact mode". (This has been in the screenshots above.) Press F8 again to restore the menus.
  • CSS lays out window panes within windows to try to organize things. You can switch quickly between sets of windows by choosing different "perspectives" using a menu item ("Windows / Open Perspective") or clicking on buttons in a task bar just under the menu bar. The first screenshot above shows a "Runtime perspective", and the second shows an "Alarm perspective".

See the SLC - Guide for more information.

How to connect to the shared control screen

Note: the shared control screen is for shifters only. For instructions on how to start your own display, see SMC - How to start your own CSS gui.
