1. A method of providing deterministic transmission of I/O data between nodes of an industrial controller communicating on an Ethernet network having a network bandwidth, the method comprising the steps of:

  • (a) communicating information between the nodes to establish a common schedule defining for each node an owned transmission time exclusive to each node so that total transmissions by the nodes during the owned transmission times consumes less than the network bandwidth; and

    (b) operating each node to transmit during the nodes owned transmission times.
