How can I communicate between two field point 2010 modules with tcp/ip?

[Fluitron]

Everytime I try to communicate with only the FP modules, communication fails. I am using the modules' IP addresses, so I doubt it is a problem with DNS. Communication works fine between a PC and FP, but never between two FP controllers

Hello Fluitron. Thank you for contacting National Instruments. The way that the FP 2010 controllers are set up, you can't communicate between the two controllers. The only way you can communicate between controllers directly would be if you had a controller that received information through a serial port. Then you could use Optimux commands to control it. Please let me know if you have any questions. Have a great day!

What sort of communication are you trying to perform between the two FP-2010s?

If you want each FP-2010 to be able to read the others IO channels, you need to use the DataSocket VIs to speak the NI Ethernet protocol instead of using the FP Read/Write/Advise VIs. Some tutorials and other information are available at the following links:

Similarly, you could have the two exchange data by having one (or both) publish software channels using the DataPublish VI, and having the other subscribe to the channel using the DataSocket VIs. An example of this is here:

Finally, if you wish to transmit string data or other types of data using TCP/IP you can using the TCP/IP VIs.

If you provide further information on the type of data you are trying to communicate between the modules, users can provide more assistance.
