Function
The product, as a station in an EtherCAT network, establishes the connection between a higher-order
controller and the modules of an automation system CPX-AP.
Device Description File
A device description file (ESI file) is used for project engineering in the EtherCAT interface of the
higher-order controller software.
It contains all the information required to configuration of the automation system CPX-AP via control
software.
The current device description file is available on the Festo Support Portal

Crossover detection (auto MDI/MDI-X)
The product supports crossover detection (auto MDI/MDI-X), which means that there is the option of
using patch cables or crossover cables.
Distributed Clocks
The product supports the "Distributed Clocks" function for precise synchronisation of stations in an
EtherCAT® network. Applications that require simultaneously coordinated actions can therefore be
implemented.
