Labview DDE with Nicolet FTIR / Omnic

[DubDee]

csedawar,

I appreciate you providing these files to the community! I hope to make them work for my project. However, your collection of files seem to have been communicating together in  a library with shared variables. I cannot even run your program because the links to the shared variables are incorrect. Is there something I am missing?  

Thanks,

WDM

Christopher:  is there any possibility for you to save the Omnic vis for Labview 8.5?

Thank you, hector

Do you have a question?

I am using a Nicolet 6700 FTIR also and am trying to control it using LabVIEW. Would you mind sharing VIs with me? Or pointing me in the right direction? This is my first experience with both softwares. Does ActiveX allow LabVIEW to control the specific functions of OMNIC without opening it? Or do you have to open both OMNIC and LabVIEW simultaneously for them to communicate?

Christopher:

Wonderfull!  Just what I need,  I have an iS5 FTIR I need to trigger.  These Vis save me from messing with the OMNIC Macro stuff and DDE.  I can open them in LV 2014 and they seem to be connecting to OMNIC s/w.  TY TY TY!!

Chris:

Great set of VIs ty, but how do you know what commands are avalable (beside the [Clear] and [Export that you use? Is this in a manual someplace?

Thank you.

I used some ActiveX with  Omnic a few years ago, with success.  But now this same code is not working with the current version of Omnic. Still works with the old one tho.  

Do you know of any change to Omnic?  or are there some settings i'm forgetting?

Does it work with Omnic light?  The Set and Get commands work but the CollectSample ignores its parameters, [CollectSample Auto Polling]  acts like just [CollectSample]

Thanx,

Bill

Bill, 

I have a client that is using a Nicolet IS-50 FTIR and the OMNIC software. I am looking at the older VIs that were written some time back and have an idea of a few of the ActiveX API commands that are exposed.

Were you able to find a comprehensive list of the API commands available through this interface? I see where you use the GET and SET Classes in the Invoke Node, but I was looking for a more comprehensive list of commands, and especially a list of commands that are usable through the Command EXE Class call in the Invoke Node.

The manufacturer eventually found a bug in there latest s/w that made my old interface fail. 

It's all fixed now.  But thank you for your replay.
