Introduction
The ER9320-0022 EtherCAT Box connects PROFINET RT networks to the EtherCAT Box modules (EPxxxx, ERxxxx and EQxxxx) and converts the telegrams from PROFINET RT to EtherCAT. One station consists of an ER9320-0022 and any number of EtherCAT Box modules. The box is connected to PROFINET via a D-coded M12 socket (in/out). With EtherCAT, the PROFINET RT box can use the lower-level, powerful, and ultra-fast I/O system with a large selection of modules. The ER9320‑0022 supports the PROFINET profile and fits seamlessly into PROFINET RT networks.
