The EL6633-0010 PROFINET RT device terminal is the successor of the EL6631-0010. It enables simple exchange of data between EtherCAT and PROFINET?RT. It is a device in the EtherCAT strand, which can consist of up to 65,535?devices. The EL6633-0010 has a 3-port switch. Two ports are fed to the outside on RJ45 sockets. This allows the I/O stations to be structured as a line topology, as a result of which the wiring is simplified. The maximum distance between two devices is 100?m. Protocols such as LLDP or SNMP can be used for network diagnosis.
