Is it possible to use NI-4351 on LabVIEW RT 8.0?

[bjla]

Hi,

I am trying to use a PXI-4351 for thermocouple measurements the controller is a PXI-8184 running LabVIEW RT 8.0.

My system was unsuccessful finding the 4351 device in MAX and I could not find a driver that supports LabVIEW 8.

Do I have to wait for a future release of the driver that supports LabVIEW RT 8 or are there any other possible solutions?

Hello!

You can use programs based on traditional NI-DAQ calls and not the 435x driver.

More information can be found here:

Regarding support for 435x devices in DAQmx I don't really know I am afraid.

How to configure a 'Traditional NI-DAQ' device under RT can be read here:

Hi

The need for LabVIEW 8 Support for NI-435x has been recognized and we hope to provide this support soon. We are currently testing such a driver and when it is available it can be found here.: NI-Drivers and Updates (http://digital.ni.com/softlib.nsf/MainPage?ReadForm&node=132010_US )

As Jimmie mentioned, the 435x devices are supported under Traditional DAQ as well. You may want to consider using example "Continuous Thermocouple Measurement.vi" that makes Traditional DAQ calls and will work in LabVIEW 8 as long as you have installed Traditional DAQ version 7.4.1.

Until a released version of the driver is ready one could do this as a workaround...

Good Luck,

1a)So I understand that at this moment the ONLY way to use my NI-PXI-4351 on my PXI LV8.0 RT target is to use tradional DAQ?

1b)Please confirm that.

2a) I downloaded the suggested Continuous Thermocouple Measurement.vi (41 kb), but could not run it on the RT target as some vi's were missing: 'conv thermo temp range....' and 'channel string to name array". So I removed these shaded onloaded vi's and put in some arbitrary constants, then I could run it, however with some erratic results, though it responded on my type-T thermocouple, just about 10°C lower than it actually was in the lab.

2b)How come?

3) Any idea when we can expect a new driver for LV8.0 RT?

Answers that can shed light on this are highly appreciated.

Hello Gerrit,

Just wanted to let you know that support for the 4351 on RT is out. It is version 2.5.1 of the drivers. You can download them under Drivers and Updates>>Multifunction DAQ

2a/b) The "Conv Thermo Temp range" VI should be added to your system when you install the traditional DAQ drivers. If it is not available it's possible that you didn't install all the examples for LV 8 and that's why the llb that includes the example is missing. I have attached it to the post.

Thanks for the info!

I will look into it.
