EK9020 | Modbus TCP/UDP Bus Coupler
The EK9020 Bus Coupler is the successor of the EK9000. It connects Ethernet networks to the EtherCAT Terminals (ELxxxx) as well as the EtherCAT Box modules (EPxxxx) and converts the telegrams from Ethernet to the E-bus signal representation. One station consists of an EK9020 and any number of EtherCAT Terminals. The coupler is connected to Ethernet via RJ45. In EtherCAT, the Ethernet 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 Modbus TCP protocol and fits seamlessly into Ethernet networks.
