摘要： A high-speed security device for network connected industrial controls provides hybrid processing in tandem hardware and software security components. The software security component establishes state-less data identifying each packet that requires high-speed processing and loads a data table in the hardware component. The hardware component may then allow packets matching data of the data table to bypass the software component while passing other non-matching packets to the software component for more sophisticated state analysis.

摘要： A network for an industrial control system employs a ring topology that is normally opened by a ring supervisor at the ring supervisor. Upon failure of the network, the ring supervisor reconnects the ring to provide an alternative transmission path around the failure point. High speed operation is reconciled with the ability to use commercial switching integrated circuits through a dual communication channel of communicating a network state as either closed or open using both high-speed hardware handled beacon frames and low-speed software processed announce frames.

摘要： A distributed control system employs a number of autonomous cooperative units that intercommunicate with bids and counter bids to allocate the production of a product among them. Network traffic caused by these bid messages is significantly reduced by creating as a central clearinghouse, a global resource locator that can identify autonomous cooperative units more likely to be receptive to bids from other autonomous cooperative units. Portions of the data of the global resource locator are held at the particular computers implementing the autonomous cooperative units in a cache-like structure that may be referred to without network communication. Misses within this cache structure cause a refreshing of the cache from the global resource locator and an updating of a learning relation table that further improves predictions in the future. Historical successes in bidding are stored at the cache structure to further aid in selecting likely bid recipients.

摘要： An operating system for distributed industrial controllers ensures the completion of enrolled application programs within a predetermined time span as is required for robust industrial control by preallocating dynamic and static hardware resources on a per application basis and in a manner that ensures execution of the application within the necessary time constraints. Portions of the distributed operating system may be distributed at particular hardware resources to provide necessary modeling for those hardware resources in making the commitments to resource bandwidths.

摘要： Multiple gateway devices communicating between a device level ring (DLR) network and a spanning tree (ST) network may be provided a gateway protocol that cooperatively ensures that only a single gateway is active at a given time. This cooperation may be effected by the transmission of advertise messages by gateways, the advertise messages holding precedence values so that only a single gateway having a highest precedence value is active at a given time. Loss of the advertise messages may trigger a gateway held in a backup state to assume an active gateway role.

摘要： Fault-tolerant Ethernet is provided through the use of special interfaces providing end-devices with duplicate ports that may be alternatively enabled with the same network address in the event of a fault detected by loss of the message from a beacon device. Unidirectional network errors in the direction from the end-device to the beacon devices are detected through a path check message from the end-device to the beacon device. Multiple faults may be accommodated without network interruption by adding top-level switches without increasing the number of ports on the end-devices by cross connecting a lowest level of switch.

摘要： The subject matter disclosed herein describes a method to allocate and prioritize data communications on an industrial control network. A transmission schedule including multiple priority windows and multiple queues is established. Each queue is assigned to at least one priority window, and each priority window may have multiple queues assigned thereto. A control device communicating on the control network transmits data packets according to the transmission schedule. Within each priority window, data packets corresponding to one of the queues assigned to the priority window may be transmitted. The data packets may be transmitted at any point during the priority window, but will only be transmitted if no data packet from a higher queue is waiting to be transmitted.
