Motivation for a control system

A5 is complex: manual operation and not practicable...

...and not possible by reason of laser safety! Communication between components is

required! Default routines have to be automatized! e.g.

automatic correction of beam position

Situation befor CS


LVOOP Objects are passiv

A5 application concept

Each physical device is represented by a LVOOP Object

Using LVOOP Design Patterns: Reference Singleton

access to object is thread safe

Integration into CS:

Create a CS Class

Forward Messages to Application e.g. over a Queue

How to integrate well working standalone application into CS-Framework ?


11

Publish Object state over DIM

Create for each LVOOP Object one DIM Service,save ID in class member variable

Update DIM Service if object data changes

Remove services at shut down

Link to device Application is established

Development of sequencers and GUIs is quite easy

Motor Calibration and Motion

Piezzo Motors Positions are not reproducible

Calibrations for +/- motions are different

also for different ranges

Changes with time

Summary: used devices


Conclusion

Combination CS and LVOOP is a convenient way of Control System development

Pump system and beamline are ready to use

A calibration solution for non reproducible motors

Convenient camera tool for daily use

first design of LVOOP Classes for Beamline


OutlookFine tuning for daily use

Automatic correction of beam position

Development of CS-based Control System for whole POLARIS lab

Nice to haveCS-Class for Bergmann Delay Cards

CS-Class for Ocean Optics Spectrometer USB2000 and USB4000
