Abstract

Method, apparatuses, and software are described, in which an adapter in an EtherNet/IP network may determine whether a first redundant owner connection between the adapter and a first scanner is open. If it is determined that the first redundant owner connection is not open, then a network status light or other indicator of the adapter may be caused to emit a solid green color or otherwise indicate a first status if a second redundant owner connection between the adapter and a second scanner is open, and to emit a flashing red color or a flashing green color (or otherwise indicate a second or third status) if no redundant owner connection to the adapter is open.
