Device Pool Status Report TANGO Collaboration Meeting April 17, 2008
Time: 11:35, 15min
Agenda
What is the Sardana DP
A software system for instrument control and data acquisition
Examples
How to write a motor controller
How to write a pseudo controller
Compare the pool with SPEC (Pool core, IPython, Macros, configuration Interface)
Pool phylosofy
Why create Sardana or Why the Sardana Layer
One could ask: Why build another layer on top of TANGO?
The alternative would be creation of a Abstract Classes
Why use Sardana
Adapter pattern (aka Wrapper)
Current status
Hope for collaboration
Robicon (aka point of no return - PNR)
Tiago Coutinho - ALBA

For those who dared to forget what sardana is
What we had 1.5 years ago
What we have now
The foreseen future
This is the part where I get on my knees and beg for collaboration

8. Current status – SardanaGUI
TANGO Collaboration Meeting 2008, April 17th and 18th 2008, Elettra
Device Pool Status Report
Current status – SardanaGUI
Configuration capabilities up to date with the pool
Actually pseudo counter configuration is missing
Possible to create a pool on a database and manage it from there on
No macro server configuration possible so far

9. Current status – Macro Server Concept
TANGO Collaboration Meeting 2008, April 17th and 18th 2008, Elettra
Device Pool Status Report
Current status – Macro Server Concept
Python device server
Initial development by Alejandro Homs & Vicente Rey
A macro execution environment
Users connect to it through a Door interface
Provides a device pool abstraction layer for the macro writer
Event based

10. Current status – Macro Server Features
TANGO Collaboration Meeting 2008, April 17th and 18th 2008, Elettra
Device Pool Status Report
Current status – Macro Server Features
Macros are stored in a repository
Macro code versions are kept and can be restored later
Macros can be changed online
Support many output levels ( debug, info, warn, error, result, info )
Data is taken and saved by the macro server
Open file format
Currently support the SPEC file format
Easy to write other output
Online data display
Data can be saved in the standard SPEC shared memory format and therefore all the ESRF online data display programs be use
Simultaneous macro execution (if there is no hardware conflict)
Macros can return values > Macro functions
Over 70 macros already available (motion, scan, data acquisition, configuration, diffractometer)

11. Current Status – Spock Concept
TANGO Collaboration Meeting 2008, April 17th and 18th 2008, Elettra
Device Pool Status Report
Current Status – Spock Concept
The ‘standard’ CLI to access the Macro Server
Initial development by Alejandro Homs & Vicente Rey
Accesses the macro server through a ‘door’
Event based
