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： An enhanced synchronized communication device within a control system may allow output data delivered to various input/output (I/O) devices to be synchronized to the time at which the output data has been generated by a programmable logic controller (PLC). In this scheme, a central processing unit (CPU) associated with the PLC may generate and transmit output data to the enhanced synchronized communication device. When the output data arrives at the enhanced synchronized communication device, the enhanced synchronized communication device may associate the output data to a trigger mechanism (e.g., the application trigger feature of Common Industrial Protocol, etc.) for immediately triggering the transfer of the output data to the I/O devices. This process may remove possible jitter associated with output data delivery in control systems.
摘要翻译：控制系统内的增强的同步通信装置可以允许输送到各种输入/输出（I / O）装置的输出数据与由可编程逻辑控制器（PLC）产生输出数据的时间同步。在该方案中，与PLC相关联的中央处理单元（CPU）可以生成并将输出数据发送到增强型同步通信设备。当输出数据到达增强型同步通信设备时，增强型同步通信设备可以将输出数据与触发机制（例如，通用工业协议的应用触发功能等）相关联，以立即触发输出数据的传输到I / O设备。该过程可以消除与控制系统中的输出数据传送相关联的可能的抖动。

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： 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 computer readable medium allow a cable break or other network link failure to be detected and reported. The method may include steps of periodically transmitting a packet from a root node in the network to a next node in the network; at each successive non-root node in the loop, manipulating the packet and forwarding the manipulated packet to a next successive node in the loop; when the packet is received back at the root node within a predetermined time period, reporting that the loop is intact; and when the packet is not received back at the root node within the predetermine time period, reporting that a network break has occurred. The network may conform to the STP or RSTP protocols, and may contain one or more rings possibly including dual rings. The PLC may operate as the root node, and the reporting may be done at an application level in the PLC.

摘要： A system, method, and computer readable medium are provided for configuring devices in a network, such as an Industrial Ethernet network. An application program includes application-specific configuration data intended to configure one or more devices in the network. The configuration data may be exported from the application and saved in one or more files. When each device boots up, it performs a network query to obtain its configuration data from a corresponding one of the files. Each device may perform a standardized network query, such as a DHCP query, to obtain preliminary network configuration data. Thereafter, the device may use another standard networking protocol, such as FTP or TFTP, to query its application-specific configuration data from a configuration file. Thereafter, the device and the application program may communicate according to the configuration parameters.
