Can a TCP HMI be used only with Labview with no PAC hardware?

[JShaw]

Hello,

I have an application where I have a DAQ board in a PC running a Labview application. I want to have a display TCP HMI in the room next door where info can be displayed as well as operator numeric input. Is this possible? If so is there an example of how to do this.

Thanks,

John

Hi John,

Yes, this is certainly possible (I am assuming this TPC is from National Instruments, and you are using the LabVIEW Touch Panel Module).  The easiest way to do this would be to use shared variables to send information over a network from the PC to the TPC.  Here is a quick tutorial specific to the TPC-2006 and LabVIEW 8.2, but the process is similar across other HW.  Some more information on shared variable support for different HW and LabVIEW versions can be found here, and in the related links sections of that page. 

Finally, there are examples of shared variable communication that install with the Touch Panel Module.  Head to the example finder (Help>>Find Examples...) and browse to Toolkits and Modules>>Touch Panel>>Networking>>General.  Here you should find some shared variable examples.  There are also some TCP & UDP examples in that Networking folder that are another option.

Hope this helps!

cheers,

Just FYI, the KnowledgeBase article linked above has been revised and moved to a new location.  See the new KnowledgeBase 58JFBGD2: Are Shared Variables Available For LabVIEW Mobile Module (Formerly PDA Modul...
