    task in

    task in is the name of the task that the operation applies.

    datatype_icon

    source

    source specifies the physical channels to use for pattern matching. The order of the physical channels determines the order of the pattern. If a port is included, the order of the physical channels within the port is in ascending order.

    datatype_icon

    pattern

    pattern specifies the digital pattern that must be met for the trigger to occur.

    datatype_icon

    error in

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

    datatype_icon

    trigger when

    trigger when specifies the condition under which the trigger occurs.

    Name Description
    Pattern Does Not Match

    Trigger when the physical channels do not match the specified pattern.

    Pattern Matches

    Trigger when the physical channels match the specified pattern.

    task out

    task out is a reference to the task after this node runs.

    error out

    error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, error out describes the error status that this node produces.

    Where This Node Can Run:

    Desktop OS: Windows
