Abstract
A method and system for interacting with data frames passing through a module connected to an industrial network is disclosed. Each module includes an aggregation unit located on the network interface above the physical layer. To transmit data, the aggregation unit reads a header from a dynamic data packet to determine if the module is a participant module for the packet. If so, the aggregation unit inserts data from the module into the data packet and transmits the packet to another module. To receive data, the aggregation unit reads a header from the data packet to determine whether the data packet includes data for the module. If so, the aggregation unit reads the data and passes the data packet to another module. If the aggregation unit determines that a data packet is not intended for the module, the data packet is passed to another module with no further interaction.
