last update: February 18, 2019
• Up to 63 NX-IO Units can be connected to one EtherCAT Coupler Unit. Standard and high-performance units can be mixed.*1
• High-speed remote I/O control is possible at the fastest communication cycle of 125 μs.*2
• Each Coupler plus its I/O form just a single EtherCAT node on the network.
• I/O control and safety control can be integrated by connecting Units for safety.
• The Coupler supports the EtherCAT Distributed Clock (DC) and propagates this to synchronous I/O units.
• The node address can be fixed by rotary switches, or set by software. Choose the method that best suits your way of engineering.
• Slave configuration by Sysmac Studio can be done centrally via the controller, or on-the-spot using the Coupler's built-in USB port.
*1 Input per Coupler Unit: Maximum 1024 bytes, Output per Coupler Unit: Maximum 1024 bytes
*2 NX7-[][][][] and NX-ECC203 combined
