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.

Drop me a private message with your email address so I can send you a reply.  Also, I couldn't seem to send you a PM just now, so you may not have that enabled on your forum account.

If you choose to post your email address on this thread, you may want to obfuscate it so it can't be scraped off by web crawling spammers.

Best regards,

Dave

Hey @valpoingenieur Since you seem to be in "new member jail", I can't PM you.  I did, however, add you to my "friends", which (in theory) should allow you access to my email address in my profile.  (Also, I PM'd the admin account and asked them to have a look at "freeing" you.)  If you can see my email. send me something so I can reply with a zip archive.

Hi David! 

I am also very interested in taking a look at your code and documentation for interfacing with Siemen's ELAN devices. 

Looks like I'm not able to private message you either. Any other way to contact you? 

Also hoping to get a hold of Kirk as well and get the Noxmat code. 

Thanks!

betancjj,

I think there's a short hold on PM permissions if you've just joined the forums.  As soon as I have your email address, I can send you a zip archive.

David,

Sounds good! Here's my email:

Thank you so much!

Hi everyone!

Having a bit of an issue with an Ultramat 6. I'm able to request CO data from the channel set for that, but for some reason requesting data from the CO2 channel returns no data. Anybody have experience with this?

I set it to Broadcast and am able to retrieve all of the data in 2 separate messages that it sends, but I'd rather request it manually if possible.

Thanks everyone!

Good morning David, Nice to meet you. I noticed from this thread I found online that you have experience with Siemens process gas analyzers (Oxymat, Ultramat, and others). Here's the link to the thread: Link I need to convert the RS485 signal output from the analyzer and interpret it to enable an IoT acquisition platform. The hardware I have available is a proprietary hardware from my company (based on Linux) that has integrated RS485 serial interfaces. How can I read the concentration values coming from the analyzers? Thank you in advance. Kindly Regards

[DavidBoyd]

Lorenzo,

It wasn't clear to me in your post whether your IoT host device runs (or can run) a LabVIEW application.  (Also, you referenced a link but I didn't find one.)  If it's some other application development platform, the best I can suggest would be to get the Siemens ELAN protocol document and start coding an application to perform the serial communication as described.

If you ARE using LabVIEW, I can send you the archive of the Siemens ELAN project library I developed.  It contains the functionality you need implemented as LV VIs and type definitions.

If you are working a different software environment and have no luck finding the protocol document, you can still PM me your email address and I can send you the PDF I have.

EDIT: another person on this thread previously provided a copy of the ELAN interface PDF, 2008 edition (it doesn't change much, this is fine):

Hi David,

Thank you for your active support on this thread over the past 20 years! Your contributions have been incredibly helpful to the community.

We are currently developing a driver in NodeJs for the ELAN protocol to communicate with Ultramat 23 analyzers. I came across your responses and found your insights on the challenges of implementing the protocol in different language environments very helpful.

I would greatly appreciate it if I could take a look at your code to use as a reference for our project. You can reach me at chen@hey.com.

Thanks again for your assistance!

Best regards,

Chen

Chen,

I used a Gmail account to send you a reply with a zip archive attached.  You can reply to that account or post back here if you'd like further guidance (since you're not developing in LV); there may be others who watch this thread who also have experience setting up and interfacing with ULTRAMAT/OXYMAT etc. who can help.

Dave
