Description
• Up to 63 NX-IO Units can be connected to one EtherNet/IP Coupler Unit. Standard and high-performance units can be mixed.*
• 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 IP address can be found on the label on the Unit, without using software.
• Slave configuration by Sysmac Studio can be done centrally via the controller, or on-the-spot using the Coupler's built-in USB port.
* Input per Coupler Unit: Maximum 504 bytes, Output per Coupler Unit: Maximum 504 bytes
