Eventually, the delay was tracked to the VISA configure serial port vi, which was taking around 200ms rather than 1ms.

For those 200ms extra to increase test time by 20 mins you'll need to configure the serial ports 6000 times ... You should really only need to configure it once at the start of program, do you reconfigure (maybe even open and close the visa) every loop?

We are upgrading our PC'S to Windows 7 64 bit. If I use Windows 7 64 bit for labview. Will it run on a Windows  XP running with 32 bit? If not from a block diagram then from a compiled version?

As long as you are using LabVIEW 32 bit on all systems, you should be OK.

(Also make sure you are using a newer LabVIEW version, one that is officially compatible with W7).

I hate the idea of not being able to use the 64 bit. I set up my PC at home for 64 bit. But I also have the PC set up to run 32 bit programs. I installed the 32 bit Windows 7 first. Then I installed the Windows 64 bit ontop of the 32 bit. This was performed under Microsoft emails. I wanted to run 32 bit and 64 bit programs.

So If I make my PC with 32 and 64 bit I can run Lab View on the 32 bit mode. 

Thanks

There are two different issues and you are confusing the discussion by not really defining what you mean.

Windows can be either 32 bit or 64 bit.

LabVIEW can be either 32 or 64 bit.

LabVIEW 32bit runs fine on windows 64bit.

I would actually recommend to use LabVIEW 32 bit on all platforms (there are probably still certain toolkits that are not compatible with labview 64 bit).

You make very little sense here. You cannot install 64 bit windows on top of 32 bit windows, I guess you replaced the 32 but OS with a 64bit version. You cannot install an OS under "microsoft emails". I don't even know what that means. 😄

I installed Windows 7 32 bit first. Then after the program was running I turned the PC OFF. MIcrosoft directions. I inserted the 64 bit version and then rebooted. The PC installed the 64 bit bit OS. I have two Program files. On shows program files 32 bit and the other is program files. I have downloded 32 bit and 64 bit programs. They are then installed in on of the two directories. So I am at a loss why my PC is able to run 32 bit applications and 64 bit applications. The installation process was sent via email and phone conversations. So I gues I am stumped on your commenst???

A plain new install of Windows 64 bit can run almost all 32 bit and 64 bit programs. This has nothing to do with the version you had installed earlier.

This is a LabVIEW support forum, and as I said, 32 bit LabVIEW runs fine on Windows 64 bit. That's all you need to know! 😄

This is a well know feature. have a look here, for example.

(If you have detailed questions about windows, you might want to ask elsewhere.)

Ok I accept your explanation. Can I develop a 32 bit labview on a 64 bit maching and then run this software on a different PC running 32 bit?

[altenbach]

yes

Thank you very much for taking the time and explaining the potential problems. I just did not want to sacrifise a 64 bit PC to a 32 bit OS.

Thank You Very much.
