When you use an embedded composite, both the structural and the parameter data are stored as part of the module (refer to the previous figure). When you edit the module in the offline view, both types of information can be modified. Double-click an embedded composite (or right-click, and then select Edit Object) to open the composite for modification.
Like in any control diagram within the DeltaV system, you can edit the parameter information when in the online view. If you created the embedded composite from a library composite, an exact copy of the library composite is made and placed within the control module. From that point forward, all links back to the original library composite are broken.
If your purpose is to create a composite that you can modify without affecting the original block or any other composite blocks that are linked to the original, embed the composite. An embedded composite is a separate, standalone object; modifying it does not change the source block, and modifying the source block does not change the new composite.
