IVI Class Driver And Installer.

[Kevin-PTP]

I am currently updating an IVI Class Driver (DC power supply) for a customer which was not approved but they now wish it to be. The original development was done in CVI6.0 and I am now working in CVI8.5. I have rebuilt it and run it through the Check IVI Specific Driver module. I have edited the driver so that all tests are passed except the following:

1. WARNING: The following Boolean, hidden, or read-only attributes do not implement range checking by any method:
2. WARNING: The FP file format version is not set to "CVI 5.5 and later".
3. ERROR: In the TQLP_GetNextInterchangeWarning Function panel:             The function panel contains a CHANGE block in the help.

How can point 1 be addressed given that they are all for booleans and a range table therefore can't be created?

How do I change the format of the FP file?

I have search through all the documentation for the function and controls and can't find a change block, is this a known issue?

Thanks in advance.

Hi Kevin,

I shall post my reply to your email here as well for others to see the answers:

 
1) The Boolean is only going to tell the user if the parameters are within a range. True/False. It is the developer’s responsibility to program logic in the driver to decide if the values are in range with the instruments.
2) You can change the FP version by navigating to the options menu in the function tree and selecting DF File Format. See attached screenshot for help.
3) I don't know what the error is for the CHANGE block, could I get more information on what is going on in the code that causes this behavior.
