Vacca 4.2

DESCRIPTION

VACCA is a versatile Control System Navigator tool built on top of the Taurus framework. It was developed by Sergi Rubio (srubio@cells.es) as the VACuum Control Application for ALBA Synchrotron.

It provides:

• Enhanced control system navigation, interactive browsing between synoptic, device tree, panels and device searching tools.

• A customizable interface, allowing user groups to have different views and configure and save their own perspectives.

• Control over tango devices and other tango services like Archiving, Astor/Starter or Tango DB properties.

• Filters at Device/Attribute/Command level, to display only the devices/attributes users are interested in.

Since Vacca 2.0 the application is build on top of taurus-gui. Its default setup includes 4 initial perspectives combining tree, synoptic, device panel, attribute grids, taurus trends and some common vacuum panels like pressure/temperature profiles.

LINKS / DEPENDENCIES

All dependencies and User Manual are available from www.tango-controls.org:

Tango PyTango Taurus Fandango

INSTALLING:

Copy vacca folder to a folder in your PYTHONPATH Copy ./vaccagui script to a folder in your PATH Copy default.py.ini to default.py and edit your default options (follow comments in the file)

For a fast way to test VACCA, try the ELINAC example:

• https://github.com/sergirubio/VACCA/blob/master/examples/elinac/README.rst

CONTENTS:

• bin/vaccagui : a launcher script

• vaccagui : an application definition for taurusgui

• vaccagui.__init__ : it loads the contents of vacca.config module

• vaccagui/default.ini : 4 perspectives by default (from showing all widgets to minimal for small screens)

• vacca : the main module

CUSTOMIZING:

The idea is to have general config in default.py (ORGANIZATION_LOGO, EXTRA_APPS, …) and use another file to customize to your beamline/system. Copy default.py to my_beamline.py; modify variables like JDRAW_FILE, COMPOSER, GRID, DEVICE, GAUGES, … Remove all variables you don’t need to modify (if ORGANIZATION_LOG is the same for all do not have it declared in many files)

RUNNING:

Launch the gui as:

./vaccagui path/to/mybeamline.py

Path to your file must be absolute or relative from “vacca” module location. If no config file is passed as argument the application will try to open $TANGO_HOST.py if exists (lazy deployment).

Creating a new default.ini:

To create a new default file for QSettings you have to remember that models must be clean up for Tree, Gauges and Profile widgets; if not the default file will not behave properly.
