Figure 7 : Smartloop Layout Example 2 : VA
Note: Unlike other Plus+ Nodes the Smartloop has no Bypass Module. In the unlikely event of the
failure of a Smartloop unit, then communications will also be lost to further Smartloops connected
downstream. Smartloops are connected to the Plus+ network via the Spur Connection (PL1) of a
Plus+ RAG Node, and so failure of the RAG Node that provides the Spur connection also results in
the failure to communicate with all the devices on that Spur.
