Control a furnace using Opc-Ua-Server

[sinan.ismael@rub.de]

Hi Everyone,

I want to connect, as client from LabVIEW, my furnace using OPC UA but actually I don't know how to start.

I downloaded the toolkit from here: https://www.ni.com/de/support/downloads/software-products/download.labview-opc-ua-toolkit.html#46761... but I can't find th Vi's in Function Palette -> Data Communication.

I also found another toolkit which I hv to pay to install it https://www.ni.com/de-de/shop/product/labview-opc-ua-toolkit.html.

Can anyone tell me which one I hv to install? Or if possible, how I can test the second one.

Thanks a lot

Hi!

There is just one OpcUa Toolkit, and you'll need a development license as well as deployment licenses for applications. There's however a trial period. Reading though the sites of your "free" link also reveals that some licenses are neccessary.

Now, did you install the correct version for your labview? Do you have the directory vi.lib\OPCUA inside your labview programm directory (like C:\Programs\National Instruments\LabVIEW 20xx)

are you using the client on the same computer as the server (e.g. localhost) - or do you use two computers?
is your opc ua server is running an generating data for your opc ua client?

are you able to connect with a non-labview opc ua client and retrieve data?

I can't tell you which LabView Toolkit  (via NI-Paketmanager) to use , but there's usually a grace period over several days before you need a licence (probably a Entwicklerlizenz, not a Verteiung Lizenz)

moreover, there may be this alternative (via VI Package Manager): https://www.vipm.io/package/grovf_lib_opc_da_client_api/

EDIT: oh, this is opc da not an opc ua
