Ethernet Communication Protocols and Standards

Various Ethernet communication protocols and standards play an essential role in ensuring robust and reliable connectivity. In this section, we will discuss some of these protocols and standards, such as the TCP/IP Stack, EtherCAT device controllers, and AVB/TSN endpoints.

Grasping these communication protocols and standards can assist you in making educated choices during the development of Ethernet-based applications for your projects.

TCP/IP Stack

The TCP/IP Stack is a widely used communication protocol for Ethernet-based applications, ensuring reliable data transfer. The TCP/IP Stack provides a suite of communication protocols necessary for Ethernet to function, enabling applications to interact with the Ethernet data link protocol (802.3) and establishing regulations and standards for communication between different layers. It enables reliable and efficient transmission of data packets between devices, thereby facilitating seamless communication and interoperability. Proper TCP IP configuration is essential for the smooth functioning of these protocols.

The TCP/IP Stack provides mechanisms for error detection, flow control, and retransmission of lost or corrupted data packets, ensuring reliable and orderly data transfer between applications or hosts. The stack encompasses four layers: the Application Layer, Transport Layer, Internet Layer, and Network Access Layer. Each layer has its own distinct functions and protocols, working together to enable communication over the internet.

EtherCAT Device Controllers

EtherCAT device controllers enable efficient communication and connectivity in industrial applications, providing rapid, real-time communication between devices in an industrial automation system. These controllers utilize the EtherCAT protocol, which operates on the MAC (Media Access Controller) at layer 2 of the Ethernet OSI model, transmitting data using standard Ethernet frames in an optimized manner. Additionally, EtherCAT is capable of operating within TSN IEEE 802.1 networks, enabling exchange between controllers with real-time requirements.

EtherCAT device controllers enhance communication efficiency in Ethernet networks by providing rapid, real-time communication between the control system and the devices in a machine or system. EtherCAT Slave devices leverage an EtherCAT Slave Controller (ESC) to process frames in real-time and entirely in hardware, making network performance predictable. Furthermore, EtherCAT employs standard, unmodified Ethernet frames and only generates one frame, liberating the CPU.

AVB/TSN Endpoints

AVB/TSN endpoints provide precise timing and synchronization for time-sensitive applications, offering improved determinism, reduced latency, and increased reliability for Ethernet communication. Technologies such as Time-Sensitive Networking (TSN) enable automatic setup and configuration, network convergence, and the segmentation of Ethernet communication into fixed lengths, facilitating more efficient and predictable communication.

AVB/TSN endpoints provide precise timing and synchronization through the utilization of TSN scheduling and the 1588 precision time protocol (PTP). TSN schedules transmissions by incorporating a timed gate control list that activates and deactivates each of the queues or traffic classes, guaranteeing that data is transmitted at regular intervals. Additionally, the 1588 PTP is employed to synchronize clocks across all media devices present on the network.

Power Over Ethernet (PoE) Solutions

Power Over Ethernet (PoE) technology is a method of providing power and data transmission over a single Ethernet cable, eliminating the need for separate power cables. This facilitates an easier and more cost-effective deployment of network devices, such as:

IP cameras
wireless access points
VoIP phones
network switches
IoT devices

PoE technology is governed by standards such as IEEE 802.3af-2003, IEEE 802.3at, and IEEE 802.3bt.

Microchip Technology offers a complete range of solutions for Power over Ethernet (PoE), including:

Integrated circuits (ICs)
Midspans
Injectors
Switches

This portfolio of PoE products covers all aspects of the solution. By leveraging PoE technology and solutions, developers can create more efficient and streamlined network deployments, reducing the complexity and cost associated with separate power and data cables.
