This example consists of both blocking and non-blocking communications VIs. There are two types of communication VIs: a server and a client. They demonstrate how to use the Advanced Communication VIs from the RCP Toolkit to establish a connection between two VI models. For a detailed description of these VIs and how they operate, please refer to the RCP CL Stream Accept, CL Stream Close, CL Stream Connect, CL Stream Flush, CL Stream Listen, CL Stream Poll, CL Stream Read and CL Stream Write help pages.

System Requirements

Please refer to the Rapid Control Prototyping (RCP) Toolkit System Requirements to run this example. This example does not require any other hardware.

Configuring the Example

Open the RCP CL Comm Advanced Stream Client Non Blocking Example.vi and the RCP CL Comm Advanced Stream Server Non Blocking Example.vi for non-blocking communications or the RCP Comm Advanced Stream Client Blocking Example.vi and the RCP Comm Advanced Stream Server Blocking Example.vi for blocking communications under My Computer. To set up the example ensure that the URI for the server and client are the same, since both VIs run on the same machine. An example of a valid URI is tcpip://localhost:18000. The RCP URIs are described on the Universal Resource Identifiers page.

Running the Example

Click on the Run button of each VI or select Run from the Operator menu to start each VI.

Move the Signal to Send knob and observe that the Received Data waveform reflects the movement of the knob at the server application.

Stop the client application. Note that the Data waveform stops plotting new data. Restart the client and see that it automatically reconnects.

Click on the Front Panel Stop button to stop the VI.
