Setting Configure Switch
Configuration of an EtherCAT board is not necessary. All settings such as communication
configuration for EtherCAT are done by EPSON RC+ 7.0.
Wiring
Wiring of an EtherCAT slave board uses RJ45 connectors. Make sure to use STP-type
100BASE-TX cables.
CAUTION

For cables and connectors, be sure to use a product complying with the industrial
standards or a noise
-resistant Ethernet cable (STP cable). If you use office use
products or UTP cables, it may cause communication errors and may not offer the
proper performance.
