摘要： 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.
摘要翻译：描述了方法，设备和软件，其中EtherNet / IP网络中的适配器可以确定适配器和第一扫描仪之间的第一冗余所有者连接是否打开。如果确定第一冗余所有者连接没有打开，则可能使网络状态指示灯或适配器的其他指示符发出固态绿色，或者指示第一个状态，如果适配器和如果没有与适配器的冗余所有者连接打开，则第二个扫描仪打开，并发出闪烁的红色或闪烁的绿色（或以其他方式指示第二或第三状态）。

摘要： Apparatuses, methods, and computer-readable media support diagnosing a communications network using a network protocol that ensures a loop-free topology to prevent bridge loops. One of the network devices is identified as a selected device in a network ring, where the selected device interacts with the network ring through first and second ports. The values of some of the parameters of the selected device are modified to be distinguishable from that of any network device in the ring, and diagnostics about the functioning of the network protocol are then performed to obtain state information about the first and second ports. When one of the ports is determined to be in the blocking state, network redundancy for the network ring is verified. However, when neither of the ports is not in the blocking state, a redundancy problem may be detected.

摘要： A networking system is discussed. The system may be used for industrial networks, where deterministic behavior is often valued. Bounded message travel times may be achieved for a first set of network traffic. Additional traffic may be routed over the networking system without interfering with the message travel times associated with the first set of network traffic. Systems and methods for assigning priority to various sets of network traffic are discussed.

摘要： A method of configuring a communication network including a network device includes obtaining a first parameter associated with a predetermined topological characteristic of the communication network, a second parameter associated with a communication protocol of the communication network and a third parameter associated with a performance characteristic of the communication network, and calculating a connection timeout value based on the first parameter, the second parameter and the third parameter. The network device is configured to determine whether a communication timeout has occurred on the communication network based on the connection timeout value. Calculating the connection timeout value may include calculating a sum of the first parameter, the second parameter and the third parameter.

摘要： A system, method, and software product are provided for updating parameters, such as requested packet intervals (RPIs), in a network. The system may include one or more PLCs, communication controllers, and I/O devices coupled in a communication network, such as EtherNet/IP. A request to change a parameter (e.g., scanning rate or timeout value) is transmitted from the PLC to an I/O device specifying a new parameter value or time-out value. The I/O device may receive the message, use a temporary time-out value while processing the message, and transmit an acknowledgement confirming the new value to the PLC. The I/O device may use the updated parameter and new time-out value. The updated parameter may be implemented without the need to take down and re-establish network connections to the affected devices.
