PyTango is a python module that exposes to Python the complete Tango C++ API. This means that you can write not only Tango applications (scripts, CLIs, GUIs) that access Tango device servers but also Tango device servers themselves, all of this in pure python.
Tango is an Open Source solution for SCADA (Supervisory Control and Data Acquisition) and DCS (Distributed Control Systems ).
Tango Distributed Control System - C++ library TANGO is an object-oriented distributed control system. In TANGO all objects are representations of devices, which can be on the same computer or distributed over a network. Communication between devices can be synchronous, asynchronous or event driven.
