Serving as an industrial gateway, this coupler enables the integration of standard digital and analog EtherCAT Terminals (EL series) and EtherCAT Box modules (EP series) into a PROFINET controller environment. The device converts the incoming telegrams from PROFINET RT to the internal E-bus signal representation, facilitating high-speed cyclic data exchange without requiring a local configuration tool.\u003c\/p\u003e\n\u003cp\u003eEquipped with an integrated 2-port switch featuring two RJ45 interfaces, the \u003cstrong\u003eBECKHOFF EK9300\u003c\/strong\u003e supports flexible line and ring topologies, which significantly simplifies system cabling and reduces the need for external network switches. The internal E-bus interface provides up to 2 A of current to supply the connected EtherCAT Terminals, making it ideal for decentralized industrial automation networks demanding robust real-time
