Re : I am looking for some information on ELAN protocol for Siemens analyzers and also some information on AK protocol for California Analytical Analyzers. Mainly I need a starting point to communicate with these devices for labview.

Thanks you very much for your email, i received it. I will work on this and will send a feedback to you.

Hi David I hope you're still reading this thread. I've recently been asked to develop a comm layer for the ELAN protocol, and I soon realized there's a lack on information on the web about it.

I read you developed VIs for it, so I'm asking where did you get the protocol specifications, and if you can share them with me.

My email is mairoldi@stasnc.it - thanks a bunch for any help you can give! 🙂

Hi Kirk

I am very interested in some example vi about AK protocol over Ethernet port.

Any help would be very welcome.

Thanks,

Thom

Hi Thom,

if you give me an email address I can send some examples to you.  Just reply to this thread.

Kirk

Kirk,

Wow, I accidently ended up on the "other" end of this thread and realized it's fully five years old.

Five years and still useful - how cool is that?

Best regards,

Dave

Hi Dave,

Good Stuff!!!

Great that people still find it useful.

Mr. Boyd your code continues to be very useful. I too have embarked on a project which uses the Siemens Gas Analyzer and I could make great use of your VIs. If you are still willing to share them please send the zip file to dclark@tecnova.com.

I ran across this thread and I believe it answers my question. I'm ordering a CAI Analyzer which uses the AK protocol and intend to communicate with the device using Labview 2009. I'm looking for a starting point for setting up communication with the device (specifically it's a 600 Series NDIR CO Analyzer). It has an option for both RS-232 and TCP, so either example would be helpful right now.

Greg,

I see this post has gone a few days without reply.  You'll need a response from EECL (Kirk at Colorado State's Engines & Energy Conversion Lab) - he's written LV code for the CAI device (also resold by Siemens).  It's a different protocol than the Siemens-developed ELAN devices (OXYMAT, ULTRAMAT).

Hopefully it's just the holiday break and he'll be back on here in a few days.
