  2. TANGO Collaboration Meeting. September 5, 6 2006 Agenda • Problem • One Solution: Device Pool • Guidelines • Device Pool Structure • Example use case

  3. TANGO Collaboration Meeting. September 5, 6 2006 Problem • How to control the experiment? • Without caring for the HW specifics • Using customized coordinate systems • Receiving constant reliable feedback • How to collect data? • In multiple formats • Automated way • How to configure new experiments? • Without having to switch the on/off button • Without being an expert SW developer • How to share configurations with different BMs? Control Room Experiment Room Motor Controllers ? . . . Counters MCAs CCDs

  4. TANGO Collaboration Meeting. September 5, 6 2006 A solution A software system for instrument control and data acquisition • Distributed • Client-server network architecture • Event driven architecture • Plug-in architecture • Scriptable • Multi-user • Open source • Allowing remote user access. • The right SW component in the right place • Easy to add/replace components Runtime add/update of new SW features • Enables creation of lightweight, platform rich client interfaces: • Java/ATK • IPython • PyQT • C++/QT,C++/MFC • etc Efficient, reliable, time consistent information feedback to the user Easy creation and deployment of new SW features We called it Device Pool

  5. TANGO Collaboration Meeting. September 5, 6 2006 Guidelines • User level abstraction • Simple client side applications • Notification based • Robust • Performance critical set of operations • Best effort approach to handle error scenarios • Script extensions • Runtime availability of new installed plug-ins • Code to handle specific HW should not be built in the system • Multiple user configurations

  6. TANGO Collaboration Meeting. September 5, 6 2006 Configuration Tool Pool Configuration API Client Applications .SO Device Pool Structure HW Motor Pseudo Motor Controller Motor Group Counter Pseudo Motor Lib Controller Lib Lib …

  7. TANGO Collaboration Meeting. September 5, 6 2006 beam motor 1 Blade 1 offset gap Blade 2 motor 2 Example use caseScenario • User doesn’t want to know about motors • 1 and 2 • He just wants to control de gap and offset • Move both at the same time • Change gap maintaining a constant offset • Change offset maintaining a constant gap • Abort movement • Control more than one motor at the same time • Provide a gap and offset motor interface • Feedback gap and offset state/status changes • Security • Prevent blades from intersecting the beam • Prevent blades from crushing to each other • Prevent blades from crushing other obstacles (ex: walls) • …
