    Merges a frame object with all child objects into the destination cluster.

    datatype_icon

    wait for complete?

    An input used to split the merging process into parts (for example, to display a progress bar).

    datatype_icon

    target cluster in

    The I/O name of the cluster where the source cluster is merged.

    datatype_icon

    source frame

    The I/O name of the frame to be merged into the target cluster.

    datatype_icon

    copy mode

    An input that defines the merging behavior if the target cluster already contains elements with the same name.

    datatype_icon

    prefix

    An input added to the source cluster name if an element with the same name exists in the target cluster.

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    percent complete

    An output used when wait for complete? is false.

    datatype_icon

    target cluster out

    A copy of target cluster in. You can use this output to wire the node to subsequent nodes.

    datatype_icon

    error out

    Error information. The node produces this output according to standard error behavior.

    Description

    This node merges a frame with all dependent child objects (PDUs, subframes, and signals) to the target cluster.

    If the source frame name was not used in the target cluster, this node copies the source frame with the child objects to the target. If a frame with the same name exists in the target cluster, you can avoid name collisions by specifying the prefix to be added to the name.

    If a frame with the same name exists in the target cluster, the merge behavior depends on the copy mode input:

    • Copy using source: The target frame with all dependent child objects is removed from the target cluster and replaced by the source objects.
    • Copy using destination: The source frame is ignored (the target cluster frame with child objects remains unchanged).
    • Merge using source: This adds child objects from the source frame to child objects from the destination frame. If the target frame contains a child object with the same name, it is replaced by the child object from the source frame. The source frame properties (for example, payload length) replace the target frame properties.
    • Merge using destination: This adds child objects from the source frame to child objects from the destination frame. If the target frame contains a child object with the same name, it remains unchanged. The target frame properties remain unchanged (for example, payload length).

    Example

    Target frame F1(v1) has signals S1 and S2(v1). Source frame F1(v2) has signals S2(v2) and S3.

    (v1) and (v2) are two versions of one object with same name, but with different properties.

    • Result of Copy using source: F1(v2), S2(v2), S3.
    • Result of Copy using destination: F1(v1), S1, S2(v1).
    • Result of Merge using source: F1(v2), S1, S2(v2), S3.
    • Result of Merge using destination: F1(v1), S1, S2(v1), S3.
