The ,centralizer element, (PLC) is an additional failure point for the system. There is no ,cent ralizer element,, thus eliminating a possible failure point. Sensors must be dedicated for connection to the PLC, thus leading to eventual duplication of sensors and additional costs in monitoring systems.
