Network variable over public internet

[Ilkka]

Dear people,

We would like to make a remote monitoring solution over the public internet.

What we need to do? I must give instructions for our customer’s IT departments..

Our system will contain data acquisition systems installed into our customers’ premises with a possibility to monitor those remotely over the internet.

Do you have any tips? Do we need to open special ports or protocols in firewalls etc.. Our current solution works nicely in LANs so that the data acquisition systems writes measured data into the same computer which is connected to NI-measurement HW. The client computers in the same LAN can connect to the server and subscribe monitored data.

We have never tested this in a WAN (Wide Area Network). One problem is that we do not have fixed IP address.. Just normal internet connections..

Now we like to take the next step and make a global remote monitoring solution and offer it to our customers.

Thank you very much for all comments,
Ilkka

Hi IIkka,

there are several options for your remote monitoring solution:

LabVIEW Web UI Builder

You first have to create a web service on your host computer (see "Tutorial: Building and Accessing a LabVIEW Web Service Application (ETS, VxWorks, Windows)" in the LabVIEW help, make sure you choose XML for the webservice output type). Then this web service can be imported into the web UI Builder.

LabVIEW Remote Panels

Go thtough the "Creating HTML Documents and Embedding Front Panel Images" Tutorial in the LabVIEW Help. If you want a remote panel of your executable then this KB might be helpful.To connect to a LabVIEW Remote Panel that is behind a remote router look at this tutorial

Hope this helps,

Hi Cheggers,

thank you for your reply. But I am not using LabVIEW 🙂

We have a .NET/Maesurement Studio based application. I would like to use the network variables for making the remote monitoring solution. It works already in local LANs between the different computers.

Please see the attached picture. At the moment the network variable is located in the server, who publish the data.

You can see the final target from the second picture.

BR,
Ilkka

Hi IIkka,

shame on me. Sorry for my post.

Unfortunately I don't know about Measurement Studio. 

Good luck to you!
