Using IVI drivers in LabView 5.1.1

Hi,

We have a set of IVI drivers ( class specific and custom specific ) developed in LabWindows/CVI 7 and IVI Compliance package 2.2 version. We want to use these drivers in a new application in LabView 5.1.1 version. I want to use the class specific drivers through the IVI class drivers in LabView 5.1.1 so as to cater for the interchangeability aspect configuring the logical names in MAX. Finally I would be creating an Installer with executable and distributing it.

I want to clarify few issues.

1. Please let me know whether I need to install any other software's apart from NI DAQ, IVI compliance package 2.2 and the Installer in the User PC. Does the IVI engine, Tool set, Class drivers for LabView 5.1.1 come with the compliance package?

2. Does MAX 2.1 support IVI drivers, interchangeability through class drivers and compliance package 2.2 or should I use MAX 3.0 for best results?

3. When I import a IVI driver (developed using IVI compliance package 2.2) to LabView 5.1.1 and try to use the functions there are some problems in the functions. As per the IVI specifications 3.2, functions GetErrorInfo and ClearErroInfo are changed to GetError and ClearError. But it shows error in the functions at those points and we have to go to IVI Error Converter.vi and change the configuration of the library node and direct it to the GetError function. Do we have an alternative to avoid this process?

It would be of great help if somebody can clear these issues.

Thanks & Regards,
Siddu

1.  The IVI Compliance Package (ICP) 2.2 installs the IVI Engine and Class Driver support for LabVIEW 7.0 and 7.1.  It does not install Class Drivers for LabVIEW 5.1.

2.  ICP 2.2 requires MAX 3.0 to get the IVI interchangeability provider in MAX.

3.  LabVIEW 5.1 was released before the official IVI specifications 3.2 were approved.  Prior to 3.2, the function names were GetErrorInfo and ClearErrorInfo.  Those changed to GetError and ClearError.  The LabVIEW wrapper generation tool that shipped with LabVIEW 5.1 is not aware of these changes.  Therefore, my suggestion is to upgrade to a later version of LabVIEW so that you will have support for the current IVI specifications and class drivers.
