摘要： Systems and methods of supporting communications over a common network connection in a master-slave field bus network with a first type of packet formatted with a time-sensitive protocol and a second type of packet formatted with a non-time-sensitive protocol are provided. The slave devices are configured with filters to prevent the first type of packet from reaching a configurator and the second type from reaching a master device. The slave devices are also configured with arbitration logic so that the packets formatted with the time-sensitive protocol are provided with a priority over the packets formatted with the non-time-sensitive protocol.

摘要： A method and system for adding a node into a network operating in a cyclic state after one or more nodes have been previously removed without interrupting the synchronous traffic of the remaining nodes on the network is provided. The method includes discovering an added node by sending data to the added node in a downstream timeslot previously assigned to a removed node, the data having a delay value for scheduling a response from the added node to coincide with an upstream timeslot previously assigned to the removed node, thereby avoiding collisions with the synchronous traffic on the network; receiving the response from the added node; configuring the added node in accordance with an original configuration of the removed node; and commencing cyclic operation of the added node.

摘要： An improved system, method, and computer-readable instructions for scheduling, transporting, and receiving inbound packets efficiently in networks with cyclic packet scheduling is provided. The method provides for scheduling upstream packet transmission slots for each node in the network so that the spacing between the packet transmission slots is reduced; for each node in the network, if there is a locally originated packet of the node to be transmitted upstream, selectively activating a forwarding buffer to receive and temporarily store a packet received from a neighboring downstream node during upstream transmission of a locally originated packet of the node; and upon completion of the upstream transmission of the locally originated packet, transmitting upstream the packet stored in the forwarding buffer.
