The EtherCAT bus coupler can automatically identify the connected bus IO modules and automatically distribute the bus IO modules to EtherCAT process images, and the EtherCAT bus coupler is used as 1 EtherCAT slave station to access the IO modules into EtherCAT real-time Ethernet through an Ethernet interface of an input/output end.

A bus coupler is a device that helps a user to dynamically switch between two or more computer buses. Unlike other bus switching methods, in which the computer must be shut down to avoid electrical problems, the bus coupler allows the user to replace the bus without going through the process. Bus couplers are of two main types, serial and cassette; although each may be used in most systems, it is directed to slightly different applications. This device is useful for network or multi-bus computers because users sometimes need different buses to handle certain problems or functions.
