LabVIEW 8.6 support for PXI-8101RT

[doy]

I have a legacy software module written with LabVIEW 8.6 real-time, but I got problems to run it on the newer PXI-8101RT real-time controller. The reason is, I cannot install RTOS on the controller using LabVIEW 8.6.1 real-time (2009 1st quarter edition). Hence, my question is, whether or not LabVIEW 8.6.1 supports PXI-8101RT?

I performed an extra step before installing LabVIEW Real-time, following the instruction on this article: "What Version of LabVIEW Real-Time or LabWindows™/CVI Real-Time is Supported by My PXI Controller and Do I Need a Target CD?". I downloaded and then installed PXI-8108 Target CD on the host computer. I then proceeded to install RTOS. I have more than 5 years of experience in working on LabVIEW real-time controllers, mostly real-time 8.2.1, so I'm confident I understand the general procedure in installing an RTOS.

The problem I encountered was, after I chose all software modules to install, and clicked ok to proceed, an error message popped up, saying "PXI Services 2.4.2 requires NI PXIe Platform Support 1.3.1". I have attached a screenshot of the error message.

Can anyone help what the error message means? and whether or not I should leave LabVIEW 8.6.1 and move to a newer version? This legacy code has CIN, which is no longer supported, so I'm wondering which version is the best to move to?

Hello Doy,

This error is caused by the version of the PXI Platform Services you are using. From the error it looks like you are using PXI Platform services 2.4.2, that does not support LVRT 8.6.1 nor the PXI 8101. The first version of the PXI Platform Services that supports both (LVRT 8.6.1 and the PXI 8101) is version 2.5.0, that actually is not availble online, the next version 2.5.1 has support for both too, and can be found on the link below:

The compatibility list for PXI hardware and LV RT can be check in the folowing links:

Thanks!

I managed to get PXI Platform Services 2.5.1 installed along with LabVIEW real-time 8.6.1. The process wasn't smooth as the installation of 2.5.x will not automatically uninstall 2.4.2. But anyways, I got that done.

The new problem is, the PXI-7833R FPGA cards (2 cards) were not recognized by the RT system. See screenshot. Should I continue to upgrade NI-RIO from 3.1 to something higher? Please see the screenshot for the details of the error. This RT controller has 2x PXI-7833R FPGA cards on Slot 2 and Slot3, and 1x PXI-6534 on Slot 4.

By taking another extra step to upgrade RIO 3.1 to RIO 3.4, the RIO error disappeared. So it's possible to install LabVIEW 8.6.1 Real-time on PXI-8101 RT by carefully choosing and installing upgrade modules.
