connect DIAdem to dstp - server

[chrisger]

hi there

i have 2 PCs connected via ethernet:

PC1: samples data with a LabVIEW executable

PC2: stores and visualize data with DIAdem

the data has to be spread over the network using a server, because there are several other PCs that want to read the data.

now here are my questions:

- can i connect DIAdem to a datasocket server?
- if not, is DIAdem shipped with a built in OPC server or something like that?

thanks in advance

Chris,

Please call me at your convenience (I'm in the office today, Thursday and Friday of this week) at (512) 683-5452, I have some additional questions and a possible solution for you.

hello Otmar,

thanks for the offer to call you. because i'm in germany i suggest to solve the problem here in this forum. this will also let others to participate on the discussion.

please post your additional questions.

many thanks

Chris,

I suggest you add the DAC Option to DIAdem (DAC Kit should work) and that has an OPC Server built in. Any external client (e.g. LabVIEW) that posts data to the OPC server should result in that data being automatically displayed in DIAdem VISUAL (which is part of DIAdem DAC, similar to the front panel in LV).

My recommendation would be to get in touch with someone at NI Germany to discuss your application and have them confirm that what you want to do can be done with DIAdem DAC.

I hope that helps,

Otmar

Hi Chrisger,

What happened to your problem later ? Have it been solved ?

Hi Otmer,

My question is exactly the same as Chrisger.

I have PC1 running Labview and execute DAQ function, and PC2 running DIAdem which will analysis the data and create a report. The two PC are connected via ethernet, now how can I transfer the data from Labview in PC1 to DIAdem in PC2 via ethernet ? I tried to use OPC but failed, because of lack of experience. 

Could anyone of you give me some instruction ?  

I have DAC function in my DIAdem 9.1.

Best regards

Somewei,

R&D just discovered a few weeks ago that the OPC connection between LabVIEW and DIAdem does not work if the "Automatically adjust clock for daylight savings changes" checkbox is selected in the Windows "Date and Time Properties" dialog on a US operating system.  We now have a fix for this issue in DIAdem 11.0 which will release with the first DIAdem 11.0 service pack (not sure when).  You might try, though, unchecking that checkbox and see if that helps on your computer.

For modern versions of LabVIEW with a shared variable engine, you can simply post data to shared variables, and they will automatically be avilable on LabVIEW's "National Instruments.Variable Engine" OPC server.  I have verified that this works on my PC with LabVIEW 8.5.1 and DIAdem 11.0 DAC, and it should work just as well between different computers.
