FAQ
===
What is the Sardana SCADA_ and how do I get an overview over the different components?
---------------------------------------------------------------------------------------
An overview over the different Sardana components is shown in the following figure:
.. image:: /_static/sardana_sketch.png
:align: center
:width: 500
The basic Sardana SCADA_ philosophy can be found :ref:`here <sardana-overview>`.
How do I install Sardana?
-------------------------
The Sardana SCADA_ system consists of different components which have to be
installed:
* Tango_: The control system middleware and tools
* PyTango_: The Python_ language binding for Tango_
* Taurus_: The GUI toolkit which is part of Sardana SCADA_
* The Sardana device pool, macro server and tools
The complete sardana installation instructions can be found
:ref:`here <sardana-getting-started>`.
How to work with Taurus_ :term:`GUI`?
-------------------------------------
A user documentation for the Taurus_ :term:`GUI` application can be found
`here <http://packages.python.org/taurus/>`__.
How to produce your own Taurus_ :term:`GUI` panel?
--------------------------------------------------
The basic philosophy of Taurus_ :term:`GUI` is to provide automatic
:term:`GUI` s which are automatically replaced by more and more specific
:term:`GUI` s if these are found.
Refer to the `user documentation on TaurusGUI <http://www.tango-
controls.org/static/taurus/latest/doc/html/users/ui/taurusgui.html>`_ for more
details on how to work with panels
How to call procedures?
-----------------------
The central idea of the Sardana SCADA_ system is to execute procedures centrally.
The execution can be started from either:
* *spock* offers a command line interface with commands very similar to SPEC_.
It is documented :ref:`here <sardana-spock>`.
* Procedures can also be executed with from a :term:`GUI`. Taurus provides
`generic widgets for macro execution <http://www.tango-
controls.org/static/taurus/latest/doc/html/users/ui/macros/>`__.
* Procedures can also be executed in specific :term:`GUI` s and specific Taurus_
widgets. The :term:`API` to execute macros from python code is documented
here **<LINK>**.
How to write procedures?
------------------------
User written procedures are central to the Sardana SCADA_ system.
Documentation how to write macros can be found :ref:`here <sardana-macros-howto>`.
Macro writers might also find the following documentation interesting:
* Documentation on how to debug macros can be found here **<LINK>**
* In addition of the strength of the python language macro writers can
interface with common elements (motors, counters) , call other macros
and use many utilities provided. The macro :term:`API` can be found
:ref:`here <sardana-macro-api>`.
* Documentation how to document your macros can be found
:ref:`here <sardana-macros-howto>`
How to write scan procedures?
-----------------------------
A very common type of procedure is the *scan* where some quantity is
varied while recording some other quantities. See the documentation on the
:ref:`Sardana Scan API <sardana-macros-scanframework>`
How to adapt SARDANA to your own hardware?
------------------------------------------
Sardana is meant to be interfaced to all types of different hardware with all
types of control systems. For every new hardware item the specific behavior
has to be programmed by writing a controller code. The documentation how to
write Sardana controllers and pseudo controllers can be found
:ref:`here <sardana-controller-howto>`.
This documentation also includes the :term:`API` which can be used to interface
to the specific hardware item.
How to add your own file format?
--------------------------------
Documentation how to add your own file format can be found here **<LINK>**.
How to use the standard macros?
-------------------------------
The list of all standard macros and their usage can be found here **<LINK>**.
How to add conditions in macros?
--------------------------------
Executing macros and moving elements can be subject to external conditions
(for example an interlock). New types of software interlocks can be easily
added to the system and are documented here **<LINK>**.
How to write your own Taurus application?
-----------------------------------------
You have basically two possibilities to write your own Taurus_ application
Start from get General TaurusGUI and create a configuration file. This approach
is documented here **<LINK>**.
Start to write your own Qt application in python starting from the Taurus_ main
window. This approach is documented here **<LINK>**.
Which are the standard Taurus graphical GUI components?
-------------------------------------------------------
A list of all standard Taurus GUI components together with screen shots
and example code can be found here **<LINK>**
How to write your own Taurus widget?
------------------------------------
A tutorial of how to write your own Taurus widget can be found
:ref:`here <sardana-screenshots>`.
How to work with the graphical GUI editor?
------------------------------------------
Taurus_ uses the QtDesigner/QtCreator as a graphical editor. Documentation
about `QtDesigner/QtCreator <http://qt.nokia.com/products/developer-tools/>`_.
The Taurus_ specific parts :ref:`here <taurusqtdesigner-tutorial>`.
What are the minimum software requirements for sardana?
-------------------------------------------------------
Sardana is developed under GNU/Linux, but should run also on Windows and OS-X.
The dependencies for installing Sardana can be found here **<LINK>**.
How to configure the system?
----------------------------
Adding and configuring hardware items on an installation is described
here **<LINK>**.
How to write your own Taurus schema?
------------------------------------
Taurus is not dependent on Tango. Other control systems or just python modules
can be interfaced to it by writing a schema. This approach is documented
here **<LINK>** and a tutorial can be found here **<LINK>**
What are the interfaces to the macro server and the pool?
---------------------------------------------------------
The low level interfaces to the Sardana Device Pool and the Macro server can
be found here **<LINK>**.
What are the data file formats used in the system and how can I read them?
--------------------------------------------------------------------------
It is easily possible to add your own file format but the standard file formats are documented here:
* The SPEC_ file format is documented here **<LINK>** and here is a list
of tools to read it **<LINK>**
* The EDF file format is documented here **<LINK>** and here is a list
of tools to read it **<LINK>**
* The NEXUS file format is documented here **<LINK>** and here is a list
of tools to read it **<LINK>**
What is the file format of the configuration files?
---------------------------------------------------
The configuration files for the Taurus_ GUI are defined here **<LINK>**.
