Hi, the cDAQ-9188 framework is perfect for my software. Since it is certainly ethernet based, I was expecting that there has been a well-defined packet file format and that I could just compose a UDP software to configure thé DAQ and after that obtain the data and blog post process it (this is definitely how the LabJack UE9 functions, for illustration). Nevertheless, as far as I can tell, this is certainly not really the situation, and National insurance proprietary code is needed to collect data from the 9188. Does anyone understand if there is a way to make use of this framework with Linux? We have a large automated test facilities built around Linux, so Linux assistance is important. Hi Eric- Unfortunately, as you have noticed, the cDAQ-9188 conversation protocol is too challenging to effectively record, and National insurance does not really currently plan (as of Might 2011) to discharge Linux drivers support in the direct potential future.
One suggestion, based on your I/U and timing requirements might become to have got a Home windows box operating NI-DAQmx that is set up to publish single-point data via the DAQmx I/O Machine and then ingested via OPC or very similar on your Linux computers. If this noises interesting I would suggest that you evaluate the MAX-based configuration described. On the other hand, you could make use of PXl DAQ with án RT system making use of the LabVIEW RT. This fundamentally allows you run some of thé newest PXIe hardware (for instance, PXIe muItifunction DAQ) on á dual-core PXle control where the 2nd core runs Linux and could connect into your existing facilities. One last choice that comes to brain would be to use for Linux and use some of the old NI DAQ hardware (for example, PCI or PXl multifunction DAQ) tó attain the exact same effect on a more standard Linux-based Personal computer.
There is a great deal of gossip in this forum from numerous customers that possess been profitable in obtaining NI-DAQmx up and working on numerous newer distros. We are usually always interested in enhancing our Linux assistance, but the marketplace demands are sometimes difficult to evaluate. If you haven't currently done so, please engage your nearby NI Industry Sales Engineer and move the requirements of your program to him therefore that we can obtain better feed-back for long term support requirements.
Ideally this assists- Tom National insurance RD. Hello Tom, thanks a lot for the fast and useful response. Please make sure to see inline: TomWDE had written: Hello Eric- However, as you possess noticed, the cDAQ-9188 communication protocol is usually too complicated to effectively record, and NI does not currently program (as of Might 2011) to discharge Linux car owner support in the direct potential future. I experienced just presumed it had been proprietary for the benefit of being proprietary. I deal with several very complex network methods in my function (eg RFC 5050) and all can become effectively noted.
The truth that it can end up being coded seems to end up being proof of this. One recommendation, depending on your I/O and time needs might become to have a Windows box running NI-DAQmx that will be configured to distribute single-point data via the DAQmx I/U Server and then ingested via OPC or identical on your Linux hosts. If this seems interesting I would suggest that you review the MAX-based settings defined.
I thought óf this, but we cán't deal with the additional over head of handling another device, especially a Home windows machine. It's less complicated to just purchase a Linux-capable DAQ, even if it't not as nice and high-quality as National insurance's equipment. Additionally, you could make use of PXl DAQ with án RT program using the LabVIEW RT. This generally enables you operate some of thé newest PXIe equipment (for illustration, PXIe muItifunction DAQ) on á dual-core PXle control where the 2nd core operates Linux and could plug into your existing facilities. This appears like something worth searching into.
I'll possess to look into how the cost/features compare to the 9188. We're also pretty allergic to LabVIEW here, therefore I'm not really certain that would take a flight unless it's i9000 just being utilized to exchange the data to the Linux side. One last option that arrives to thoughts would be to use for Linux and make use of some of the old NI DAQ hardware (for instance, PCI or PXl multifunction DAQ) tó achieve the same effect on a more regular Linux-based Computer. There is definitely a lot of chatter in this community forum from different customers that have got been prosperous in obtaining NI-DAQmx up and operating on several newer distros. Hmm, the reality that this is definitely backed by discussion board chatter appears to indicate that either the driver is rather older or can be half-baked. We are usually always interested in enhancing our Linux assistance, but the market demands are usually sometimes tough to determine.

If you haven't currently done so, please indulge your nearby NI Industry Sales Engineer and move the needs of your program to him therefore that we can obtain better feedback for upcoming support needs. Having worked well with several DAQs in the past, I can say this is definitely a perennial issue with NI. Great hardware, but missing Linux support. IMHO I believe you may not really be obtaining a full watch of the possible market since your products seem to become targeted primarily at scientists as compared to EE/CE people.
