Beckhoff EL6022 communication interface

The EL6022 is a two-channel serial interface terminal from the Beckhoff EtherCAT Terminal series, designed for RS422 and RS485 serial communication. It provides two independent configurable serial ports directly within the EtherCAT I/O system, allowing the controller to communicate with multiple industrial devices such as drives, sensors, meters, and legacy equipment over differential serial links. Data is exchanged transparently over EtherCAT, making the EL6022 a compact solution for integrating multiple RS422/RS485 devices into modern automation systems.
