FAQ for NX-ECC203
What controllers work with NX-ECC203?
NJ/NX series machine controllers (EtherCAT master), third-party EtherCAT masters (Beckhoff, TwinCAT, etc.). Any EtherCAT master can control NX I/O via ECC203.
How many NX I/O units can I connect?
Maximum 64 NX units per coupler. Limited by power budget and I/O capacity. For more I/O, add additional couplers on same EtherCAT network.
What's the advantage of EtherCAT?
High speed (0.5ms cycle), long distance (100m between nodes), simple topology (daisy-chain), multi-vendor compatibility. Ideal for distributed I/O systems.
Do I need to configure each I/O unit?
No, NX-ECC203 auto-recognizes connected NX units. Configuration done in Sysmac Studio: add coupler to network, I/O allocation automatic.
