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

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

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

14. Why monitors?
PVs
Sergei Chevtsov,

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

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

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

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

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

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

23. aidalist aidalist(device, attribute)
Lists attributes of the specified device (use % as wildcard), e.g.
>> aidalist('QUAD:LI01:221', 'Z%')
password:
QUAD:LI01: Z
QUAD:LI01: ZTIM
ans =
Sergei Chevtsov,

24. aidaget aidaget(‘<device>//<attribute>’)
Gets value of the specified device attribute e.g.
>> aidaget('QUAD:LI01:221//ZTIM')
ans =
e+12
