EtherCAT connection

The latest generation of Embedded PCs can be ordered with the optional EtherCAT slave interface (B110). The optional interface B110 is identified as X300 on the devices and has as black border to identify it.

EtherCAT connection 1:

The incoming EtherCAT signal is connected to the upper port of the X300 interface. The lower port forwards the signal to further EtherCAT slave devices. Up to 480 bytes of input and output data or 256 variables can be connected via the EtherCAT interface.

It is not possible to create 480 bytes individually, for sample, since this would require 480 variables.
