A. Kessler, CS-Workshop 2012, CS- Framework at POLARIS 7 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

A. Kessler, CS-Workshop 2012, CS-Framework at POLARIS 10/21 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 Main.vi User events Loop User events Loop CAN Bus Loop CAN Bus Loop Watch Dog Loop Watch Dog Loop LVOOP Objects Main.vi: some Loops for managing device states and communication pump control.thread.vi User events Loop User events Loop CAN Bus Loop CAN Bus Loop Watch Dog Loop Watch Dog Loop LVOOP Objects CS Framework Messages receive Loop CS Framework Messages receive Loop 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 ?

A. Kessler, CS-Workshop 2012, CS- Framework at POLARIS 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

A. Kessler, CS-Workshop 2012, CS- Framework at POLARIS 17 Motor Calibration and Motion Piezzo Motors Positions are not reproducible Calibrations for +/- motions are different also for different ranges Changes with time Cam Adjustment Motor DB returns last calibrations most appropriate calibration will be selected dependent to misalignment

A. Kessler, CS-Workshop 2012, CS-Framework at POLARIS 19/21 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

A. Kessler, CS-Workshop 2012, CS-Framework at POLARIS 20/21 Outlook Fine tuning for daily use Automatic correction of beam position Development of CS-based Control System for whole POLARIS lab Nice to have CS-Class for Bergmann Delay Cards CS-Class for Ocean Optics Spectrometer USB2000 and USB4000
