Open multiple ports using NI web server.

[ttkmhi3]

Hi!
I'm currently developing web application using Labview NXG web module and Systemlink.

Using the one PC, I would like to display Systemlink tag value on web browser that builds Labview NXG web module.

I try to write Systemlink tag using HTTP port 8000,read and display Systemlink tag value by web browser using HTTP port 80.

NI web server configuration can setting only one port number.
it open only one of port 80 and 8000.

Could it open multiple ports using NI web server?

I consider using two PC.

Thanks.

Hello,

We are using quite a bit of SystemLink Tags and NXG Web Modules at our facility.

Could you provide an example of the code you are using for this application? So I can understand a little better on what you are trying to accomplish here!

Thanks!

Hi ttkmhi3, 

There is is no need to read and write to SystemLink tags using different ports. This isn't possible. We encourage reading and writing tags via HTTP (this is the default for VIs and WebVIs). The default HTTP port in SystemLink is port 80. 

Is there a question behind the question? Why do you want read vs write operations to be on different ports?

Dear MarkBlack , CMullinsEE

Thank you for your reply.

This issue has been resolved.

I was able to read and write on port 80 using Systemlink Tag.

I had the wrong idea that the port used by WebVI and Systemlink Tag should be different.
