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.
Claims18
A method, comprising:
- determining, by an adapter device in an EtherNet/IP network, whether a first redundant owner connection between the adapter device and a first scanner device is open;
- and
- if it is determined that the first redundant owner connection is not open, then causing a network status indicator of the adapter device to indicate a first status if a second redundant owner connection between the adapter device and a second scanner device is open, and to indicate a second status or a third status if no redundant owner connection to the adapter device is open.
An apparatus, comprising:
- a processor;
- a network status indicator;
- and
- a communication interface configured to be coupled to a network,
- wherein the processor is configured to:
- cause the network status indicator to indicate a first status when at least one of a plurality of redundant owner connections to the communication interface is open, even if another of the plurality of redundant owner connections is closed or timed out, and
- cause the network status indicator to indicate a second status or a third status when there are no open redundant owner connections to the communication interface,
- wherein the apparatus comprises an adapter and the network comprises an EtherNet/IP network.
An apparatus, comprising:
- a processor;
- and
- a network status light,
- wherein the processor is configured to:
- determine whether a first redundant owner connection between the apparatus and a first scanner is open;
- and
- if it is determined that the first redundant owner connection is not open, cause the network status light to emit a solid green color if a second redundant owner connection between the apparatus and a second scanner is open, and to emit a flashing red color or a flashing green color if no redundant owner connection to the apparatus is open,
- wherein the apparatus comprises an adapter configured to communicate with an EtherNet/IP network.
