We are happy to bring you the improved version of our
LabVIEW-EPICS-interface CA Lab 1.4.1.0!

http://www-csr.bessy.de/control/SoftDist/CA_Lab/

Change-log of CA Lab
V1.4.1.0 (Released: February 2013)
  + New memory management
  + Gaps in string arrays are possible now; e.g. ['a', 'b', '', 'd']
    (EPICS data type must be a string array!)
  + New LabVIEW control "PV Info" (output cluster),
    project "CaLabs.lvproj" and aliases "CaLabs.aliases"
    (Thanks to Robert M. Everly)
  + Global Channel Access warnings and errors are displayed
    via "Debugging window" of LabVIEW
  # Just one call of caLab.dll in caLabGet.vi instead of two
  # Parallel running instances of CA Lab don't freeze anymore
  # Events: Initially disconnected variables receive values
    after connection is established (fix)
  # Improved LabVIEW convention of VIs
    (Thanks to Robert M. Everly)
  # Update of ReadMeFirst.txt
  # Delayed termination of VIs if they run a very short time (<10sec.)
    This guarantees a safe termination of EPICS environment.
  # Write values (without synchronous) is up to 10 times faster now
  # Read values is up to 5 times faster now
  - Removed buffer size (since version 1.3 without function)
  - Removed dead lock detecting and auto unfreezing
    (No workaround needed anymore)

*** Note ***
If you upgrade existing VIs with CA Lab please exchange:
    caLabGetxx.vi -> caLabGet.vi
    caLabPutxx.vi -> caLabPut.vi
and click right on greyed out CA Lab VIs and use "Relink to SubVI"
to update type of Polymorphic VI.
Watch out! LabVIEW may result in a misalignment of connectors!!


All suggestions and comments are welcome!

Cheers
Carsten
