Inputs/Outputs

  • cu16.png port or service name —

    port or service name can accept a numeric or string input. port or service name identifies what port to write to. If you specify a service name, LabVIEW queries the NI Service Locator for the port number that the server registered.

  • cu32.png address —

    address is the address of the computer where you want to send a datagram.

  • cudpncrn.png connection ID —

    connection ID is a network connection refnum that uniquely identifies the UDP socket.

  • cstr.png data in —

    data in contains the data to write to another UDP socket.

    In an Ethernet environment, restrict data to 8192 bytes. In a LocalTalk environment, restrict data to 1458 bytes to maintain gateway performance.
  • ci32.png timeout ms (25000) —

    timeout ms specifies the time, in milliseconds, that the function waits before the function completes and returns an error. The default value is 25,000 ms or 25 seconds. A value of -1 indicates to wait indefinitely.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • iudpncrn.png connection ID out —

    connection ID out returns the same value as connection ID.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
