The ACNET system monitors many different variables, which can be viewed anywhere using the synoptic page. Synoptic is a client-server system for graphical data representation.
It is similar to ACNET Lex SA and EPICS EDM applications.
The displays can run either within a Java application, or in a conventional web browser as "live" SVG images. In a web page mode internet browser generates .svg images of the displays, so you will not be able to
get access to the displays with the control/set capabilities. Live web pages are intended for the quick review of the detector status.
Gaining control/set capabilities requires Java Runtime Environment.
Below is the list of pages, from which you can access the synoptic displays for NDOS, Near and Far Detectors.
http://novadcs-far-master-01.fnal.gov:8000/synoptic/ (Need VPN + MIT Kerberos Ticket if off site), or
http://synoptic.fnal.gov/novafar/ for a web display-only for offsite (quick view of data without control/set capabilities).
The synoptic pages are always running in the control room, and a DCS expert as well as the shifter should be familiar with the synoptic pages and what is displayed on them.
The ACNET server computers are novadcs-far-readout-0X where X is 1, 2, 3, or 4. There is also a data logger for viewing historical data (DocDB # 8900 or the Sensor-log Analysis expert's page here).
Editing / Creating Synoptic Displays¶
Detailed documentation can be found http://synoptic.fnal.gov/doc/index.html.
The following video was created by the developers as a reference material for editing and creating Synoptic Displays.
The URL of the video is: http://vmsstreamer1.fnal.gov/Training/AD/120302ADSynoptic/index.htm
If you are not an experience Synoptic developer, DO NOT edit displays in the central repository.
Download the entire Display tree into your local disk and edit it there.
To Download the Display tree:
1. Double click on Launch Builder. This will prompt you to run the .jnlp java script. Running the script will open
the Synoptic builder window.
2. From the menu on the left go to CVS and click Reload Tree. This will create a Synoptic directory on your local disk with links to actual displays. It will not download the actual display.
3. To access and edit displays, open the builder window by running java script from the website. Do reload tree.
4. Once you are happy with changes to the display, do File->Save. This will save the changes to your local disk. It will not change the repository.
5. When the changes to the display are confirmed to be working and you have obtained permission from the Run Coordinator you can commit the changes to the repository by Right-Clicking the display from the CVS menu on the right and selecting Commit(Check In).
