Is "write to digital line.vi" compatible in LabVIEW 7.0

[USCORNLUW]

I developed a LabVIEW program to change the logic state of a digital line using the "write to digital line.vi". This was first done in labVIEW 6.1. The version was later upgraded to LabVIEW 7.0 later and the VI doesn't seem to perform the function correctly, meaning when I tried to change the line state from "low" to "high", it doesn't seem to be doing anything. Is this because of compatibility issue of "write to digital line.vi" with LabVIEW 7.0? Thanks!

There should be no problem using the traditional DAQ driver in 7.0. After installing 7.0, did you reinstall traditional DAQ? Does the traditional DAQ driver show up in MAX? Do you get any error when you run the VI?

Yes, the traditonal NI-DAQ still shows up in MAX under software as well as the Devices and interfaces (because I have traditional NI-DAQ (legacy) devices). Can I have both the traditional NI-DAQ and the NI-DAQmx on my computer? When we first ran it, it did come up with a error message. But after we installed the legacy NI-DAQ (I guessed it is the traditional Ni-DAQ), the error goes away. Could you read anything from it? Thanks a lot!

The two can coexist though it has been quite a while since I've had to do it. The thing to make sure is that if the card is supported by both drivers, that the driver you want to use is the active one. You can check and reset it in MAX.
