Consideration on connecting long distance between real-time target and host

[Yaovaja]

I am considering on connecting long distance between real-time target and host.

I am going to build a system which the remote(host) computer has to be far long distance from its real-time target.

It's approximately 300 meter.

I will use TCP/IP with UTP lan harness, all I know, it works only for 100 meter.

Some recommendation is to use switching/hub connect at each 100 meter-length UTP lan.

Will this work with LabVIEW, NI CRIO, real-time configuration?

What is your recommendation?

Thank you very much.

Hello Yaovaja,

As I understand, your potential system would have the following configuration:

host computer --> 100m --> switch/hub --> 100m --> switch/hub --> 100m --> cRIO

With this setup and the 100 meter specification you mentioned, you should be able to communicate from the host computer to the cRIO over TCP/IP. Thus, this setup should work for your application.

For ease of setup, I recommend initially connecting your cRIO either directly to or on the same subnet as your host computer. That way, you can detect the cRIO and set up it's IP address.

If you run into issues, a very useful link is Why Does My CompactRIO Controller Not Show Up in Measurement & Automation Explorer?. Please let me know if you have related questions.
