Inputs/Outputs

  • cstr.png target address (localhost) —

    target address specifies the IP address or DNS name of the target.

  • cu32.png scan period (uSec) —

    scan period (uSec) specifies the period for the scan engine running on the target.

  • cerrcodeclst.png error in (no error) —

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

  • ierrcodeclst.png error out —

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

    • Changing the scan period while the scan engine is running can take a significant amount of time, and might cause the scan engine to run late, resulting in a major fault. If changing the scan period results in a fault, you can safely clear the fault after the new scan period takes effect.

    Note If the target includes an expansion I/O driver, you can set the scan period only when the NI Scan Engine is in Configuration Mode. You can use the Set Scan Engine Mode VI before this VI to put the NI Scan Engine on the target into Configuration Mode.
