Signal Bridges

Signal bridges are elements that copy the values from one attribute to another. Each bridge consists of a number of connection between a readable attribute of a Xentara element, and a writable attribute of the same or of a different Xentara element. Whenever the copy operation is triggered, all the values are read from the source attributes and copied to the corresponding target attributes.

Normally, a signal bridge only copies the attribute values in the operational stage. A bridge can be configure to copy the values in any stage, however.

Signal bridges expose a single task named copy that performs the copying. You can insert that task into an execution pipeline and attach it to a timer or an event.
