Version information
===================

The LMC controller device is able to give the version information of the
currently running SDP system. This information includes the component version
information.

The version information is returned as a string. It shows only the enabled
components. If a new version of the components is deployed, or a new version
of the SDP is deployed, then this version information will update.

Usage
-----

To get the version information you need to access the controller device via the
Tango interface.

For example using ITango:

.. code-block:: python

    In [1]: import json

.. code-block:: python

    In [2]: controller = Device("test-sdp/control/0")

.. code-block:: python

    In [3]: json.loads(controller.sdpVersion)
    Out[3]:
