EtherCAT (Ethernet for Control Automation Technology) is a high-performance network protocol designed for industrial automation. It allows multiple devices to communicate in real-time over standard Ethernet cables, making it efficient for controlling machinery and processes. EtherCAT is known for its fast data transmission and low latency, which are crucial for applications requiring precise timing. The protocol operates using a master-slave architecture, where one master device controls multiple slave devices. This setup enables seamless data exchange and synchronization among devices, such as sensors, actuators, and controllers. EtherCAT is widely used in various industries, including manufacturing, robotics, and process control.
