  10. LabCA PVs Model LabCA AIDA Matlab (32 bit Linux) Sergei Chevtsov, 02-07-2007

  11. LabCA • Matlab functions • Names begin with “lca” Most commonly used: • lcaGet • lcaPut • lcaSetMonitor/lcaNewMonitorValue Sergei Chevtsov, 02-07-2007

  12. lcaGet [value, timestamp] = lcaGet(pv) Gets PV value, e.g. >> lcaGet('MIKE:BEAM') ans = 'ON' Sergei Chevtsov, 02-07-2007

  13. lcaPut lcaPut(pv, value) Sets PV value, e.g. >> lcaPut('MIKE:BEAM', 'OFF') Sergei Chevtsov, 02-07-2007

  14. Why monitors? PVs Sergei Chevtsov, 02-07-2007

  15. Why monitors? PVs for i=1:n get; Repeated data retrieval Sergei Chevtsov, 02-07-2007

  16. Why monitors? PVs • …but no new data yet • network overload • complex algorithms for i=1:n get; Sergei Chevtsov, 02-07-2007

  17. Why monitors? PVs for i=1:n waitAndGet; Wait until new data, then retrieve it Sergei Chevtsov, 02-07-2007

  18. lcaSetMonitor lcaSetMonitor(pv) Sets PV monitor, e.g. >> lcaSetMonitor('MIKE:BEAM') Sergei Chevtsov, 02-07-2007

  19. lcaNewMonitorValue flag = lcaNewMonitorValue(pv) Returns whether a new PV value available, e.g. >> lcaNewMonitorValue('MIKE:BEAM') ans = 1 Sergei Chevtsov, 02-07-2007

  21. AIDA PVs Model LabCA AIDA Matlab (32 bit Linux) Sergei Chevtsov, 02-07-2007

  22. AIDA • Matlab functions • Names begin with “aida” Most commonly used: • aidalist • aidaget Sergei Chevtsov, 02-07-2007

  23. aidalist aidalist(device, attribute) Lists attributes of the specified device (use % as wildcard), e.g. >> aidalist('QUAD:LI01:221', 'Z%') chevtsov@flora's password: QUAD:LI01:221 Z QUAD:LI01:221 ZTIM ans = 0 Sergei Chevtsov, 02-07-2007

  24. aidaget aidaget(‘<device>//<attribute>’) Gets value of the specified device attribute e.g. >> aidaget('QUAD:LI01:221//ZTIM') ans = -2.8622e+12 Sergei Chevtsov, 02-07-2007
