Outlines of the configuration devices are given below.
EtherCAT Master
The EtherCAT master manages the network, monitors the status of slaves, and exchanges I/O data
with slaves. There is one output port.
Output Port
The output port transmits EtherCAT communications data to other devices. When you connect the
output port to another device, always connect it to the input port on the other device. Normal com-
munications will not be possible if you connect to the output port on another device.
