3. What is Tango?
A toolbox to implement control systems using CORBA as the transport layer
A specialization of CORBA adapted to Control
Hides the complexity of Corba to the programmer
Adds specific control system features
CORBA
TANGO
Control System

4. CORBA Common Object Request Broker Architecture
CORBA defines the ORB: a way to call an object “method” wherever the object is
In the same process
In another process
In a process running somewhere on the network
CORBA also defines services available for all objects (naming, notification, event)

5. CORBA CORBA allows mixing languages:
a client is not necessarily written in the same language as the server
CORBA uses an Interface Definition Language (IDL)
CORBA defines bindings between IDL and the computing languages (C++, Java, Python, Ada, ….)

6. Tango and CORBA Tango encapsulates the CORBA communication protocol
Allows the use of other communiction protocols
Tango uses a narrow CORBA interface
All objects on the network have the same interface
Allows the use of generic applications
Avoids recompilation when new objects are added

8. What is Tango?
Provides an unified interface to devices (objects) on the network
hiding how they are connected to a computer (serial line, USB, sockets, …)
Hides the network
Location transparency
Genericity
APIs for C++, Python and Java
For the server and the client side

9. What is Tango? More than only a software bus Database for persistancy
Code generator to implement networked devices
Central services (Archive, snapshots, logging, alarms, scans, security, …)
Application Toolkits (Java, C++ and Python)
Comercial bindings (Labview, Matlab, IgorPro)
Control system administration (Starter, Astor)
Hundrets of available classes
Web interfaces (PHP, Java)

15. How to dance the Tango? Lets dance together:
Two collaboration meetings per year
A mailing list
One Tango coordinator per site
WEB site to download code, get documentation, search the mailing list history, read collaboration meeting minutes, …
Collaborative development using SourceForge

16. How to dance the Tango? You can download Tango from
As a source package for UNIX like OS
As a Windows binary distribution
For Unix (and co), do not forget to first download, compile and install
omniORB
omniNotify
For Windows all libraries and binaries for omniORB and omniNotify are included in the distribution.

17. How to dance the Tango?
A list of all Tango classes is available with their documentation under
Common interest class sources are stored on a CVS server hosted by SourceForge
Project name = tango-ds
Local class sources are stored in a local CVS repository at each institute
