# Introduction ### What is EtherCAT®? EtherCAT® (Ethernet for Control Automation Technology) is a high-performance Ethernet Fieldbus technology that provides a reliable, efficient, and cost-effective communication solution for a wide variety of industrial automation applications. Originally developed as an open technology by Beckhoff Automation in 2003, and subsequently turned over to an independent organization known as the EtherCAT® Technology Group, EtherCAT® has since become one of the most widely used industrial Ethernet protocols in the world. #### SEE ALSO A comprehensive introduction to EtherCAT® technology can be found at [https://www.acontis.com/en/what-is-ethercat-communication-protocol.html](https://www.acontis.com/en/what-is-ethercat-communication-protocol.html).
