OPEN REAL-TIME ETHERNET PROTOCOL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18735578 titled 'OPEN REAL-TIME ETHERNET PROTOCOL

The patent application describes a real-time Ethernet (RTE) protocol that includes start-up frames for network initialization and data exchange frames for communication between master and slave devices.

• The start-up frames include device Discovery frames, Parameterization frames, and Time Synchronization frames to set up the network and synchronize communication between devices.
• The data exchange frames exclude source and destination addresses, containing a header to differentiate between master and slave, a type field, a status field, and a data payload for actual data transmission.
• The protocol allows for dynamically switching between different frame forwarding modes based on the current protocol state indicated in the status field of the start-up frames.
• Each slave device is assigned unique communication time slots by the master device in the Time Synchronization frames, ensuring efficient and synchronized data exchange.
• The protocol streamlines network initialization and data transmission processes, enhancing the overall efficiency and reliability of Ethernet communication in real-time applications.

Potential Applications: - Industrial automation systems - Robotics - Process control systems - Automotive networking

Original Abstract Submitted

A real-time Ethernet (RTE) protocol includes start-up frames originated by a master device for network initialization including a preamble, destination address (DA), source address (SA), a type field, and a status field including state information that indicates a current protocol state that the Ethernet network is in for the slave devices to translate for dynamically switching to one of a plurality of provided frame forwarding modes. The start-up frames include device Discovery frames at power up, Parameterization frames that distribute network parameters, and Time Synchronization frames including the master's time and unique assigned communication time slots for each slave device. After the initialization at least one data exchange frame is transmitted exclusive of SA and DA including a preamble that comprises a header that differentiates between master and slave, a type field, a status field excluding the current protocol state, and a data payload.
