February 18, 2010Dietrich Beck CS-Status Results from workshop 2009 – what was planned for 2009 – what was done in 2009 Statistics Miscellaneous

February 18, 2010Dietrich Beck Results from CS Workshop 2009, I FPGA as pattern generator –new package CNI_FPGA_PPG, contains –class NI_FPGA_PPG FPGA code, instrument driver, class author: Falk Ziegler, slight modifications maintainer: Dietrich Beck suffices Greifswald –class PPG_ABC author, maintainer: Dietrich Beck derived from NI_FPGA_PPG extension for others using "abcDE" pattern definitions Requires modifications for MM6.vi –in use at SHIPTRAP –seems to work... Changes for MM6.cpp would be nice (trigger definition etc...)

February 18, 2010Dietrich Beck by the way (1): TTL Line-Driver Module Harald Hahn, GSI select I/O for each line 40 lines per module 4 modules per 19" crate max 100mA (50Ω) per line max 6A per crate delay time 80ns rise time 50Ω optional remote control –invert line –direction –buffer function –... in use at SHIPTRAP...

February 18, 2010Dietrich Beck by the way (2): FPGA as Multi-Channel-Scaler three TTL I/O –start trigger (input, positive edge, logic high) –signal (input, positive edge, logic high) –isActive (output, logic high while counting) FPGA over-clocked to 80 MHz (could be even more) –minimum time for active high is 12.5 ns –maximum count rate 40 MHz requires "NIM-electronics-type" discriminator and gate simple FPGA program and instrument driver –small amount (kBytes) of data, handled by DMA transfer –fits easily into the 7811R

February 18, 2010Dietrich Beck Results from CS Workshop 2009, II (not yet) final maintenance release for LV 8.2.1: CS 3.13 change of LabVIEW version from to (no) anyway: some users started using CS 3.1X on already questionnaire: LV or directly LV 2009?  Holger

February 18, 2010Dietrich Beck Progress in the Past Year (1) mainly maintenance and support work –bug fixes –updated packages –one release of package CSMain –present version CS 3.13 (no active patch, but changes in SCC) –remote shutdown of CS systems via the DMS Server –changed "Unpackager" a couple of times  discussion! –new SourceForge web-site  using VI-Analyzer to check code quality of released packages using CS2Java (slightly hacked) for class documentation of packages recently released in preparation: CS version 3.14 as the final maintenance release for LV 8.2.1

February 18, 2010Dietrich Beck Progress in the Past Year (2) new class DeviceBaseGUI –reduces "copy and paste" for GUI classes (especially for GOGs) –eases development of GUIs for GOG –required slight changes for the GOG GOG slightly changed to ease to create user specific GUIs

February 18, 2010Dietrich Beck Statistics from SourceForge among top 1% (almost) of SourceForge projects > 2600 (until 2009: 1400) downloads of CSMain 34 (2009: 31 packages) of 2 maintainers 70 total, 4 open (2009: 51/1) bugs 47 total, 12 open (2009: 41/7) feature requests 26 total, 2 open (2009: 25/2) patches 3 total, 0 open (2009: 3/0) support requests 9 (2009: 9) developers

February 18, 2010Dietrich Beck Usage of the CS framework today experiments requiring high flexibility experiments with a large variety of hardware types experiments with up to 10,000 (1M possible) process variables PHELIX PHELIX Motion CaveA SHIPTRAP ISOLTRAP REXTRAP REXTRAP LEBIT LEBIT GSI, Germany Mainz, Germany Greifswald, Germany CERN, Switzerland MSU, USA Lanzhou, China data taking development commissioning Motion CaveA FOPI RISING others... HITRAP LPT ClusterTRAP WITCH TrigaTRAP

February 18, 2010Dietrich Beck Other Issues, Outlook change pattern generator of trap control systems for other too HITRAP maintenance (just cumulative patches) release CS 3.14 in summer 2010, based on LV (final release for 8.2.1?) upgrade to LV X new classes for application layer: ControllerBase, GOGController, GOGControllerGUI

February 18, 2010Dietrich Beck ControllerBase et al. a control system is composed of a main system and sub-systems each system has an application layer object derived from ControllerBase ControllerBase and derived classes have a state machine with sub-systems: state machine hierarchy –states propagate up (DIM services) –commands are executed and sent down (DIM commands) application layer objects control device objects and their settings

February 18, 2010Dietrich Beck ControllerBase et al. continued GOGController class –application layer class derived from ControllerBase –uses the GOG class to manage devices LoadSettings SaveSettings Execute(All) GOGControllerGUI –associated to the GOGController class –just provides methods useful for GUI classes –base class for building experiment specific GUIs –idea experiment specific GUIs mainly programmed with plain LabVIEW

February 18, 2010Dietrich Beck State Machine

February 18, 2010Dietrich Beck Why GOGController and...GUI immediate visual feedback from the control system via the state of the "main system" simple interaction –Configure (configID) –SaveConfig ((another)configID –PrepareForOperation –(Recover, Reset) –can be automated device control –via prepared GUI elements –behind the scenes: use infrastructure provided by GOG class easy to maintain/change using standard LabVIEW virtual facility
