Abstract:
1. An industrial communication network for real-time control connecting at least three nodes for bidirectional communication via a network medium, comprising: at least two end nodes, each end node including a network interface configured to execute in a first mode of operation to initiate transmission of a data frame via the network medium to at least one other end node, wherein the data frame further includes a unique identifier, a frame priority, and a structured data block, and wherein the unique identifier is a function of the end node from which it is initiated and of the data block contained within the data frame; and at least one intermediate node including a network interface configured to operate in a second mode of operation to perform the following steps: receive data frames from each of the end nodes, select data frames as a function of the unique identifier, extract data from or insert data to a predefined position of the structured data block of the selected data frame without passing the data frame through the protocol stack, and transmit the data frame to the other of the end nodes.
