The EK9300 Bus Coupler connects PROFINET RT networks to the EtherCAT Terminals (ELxxxx) as well as the EtherCAT Box modules (EPxxxx) and converts the telegrams from PROFINET RT to the E-bus signal representation. One station consists of an EK9300 and any number of EtherCAT Terminals. The coupler is connected to PROFINET RT via RJ45. In EtherCAT, the PROFINET RT coupler has at its disposal a lower-level, powerful and ultra-fast I/O system with a large selection of terminals. The coupler supports the PROFINET RT profile and fits seamlessly into PROFINET RT networks.
