Architecture Performance Data

Industrial Network Protocol Integration

The controller utilizes an integrated EtherCAT Master interface to maintain ProFINET / EtherNet/IP deterministic networks synchronization across remote field nodes. High-speed backplane bus communication velocity handles processing loops across local CJ I/O bus expansion racks, providing firmware flash compatibility and scalable I/O density scaling up to 40 expansion units.

System Mount & Communication Setup Guidelines

Rack Assembly Mechanics

Mount the NJ1 CPU onto a standard DIN rail rail assembly. Secure the CJ I/O bus end cover on the rightmost expansion unit to maintain bus continuity and electrical stability.

Bus Cable Routing

Connect EtherCAT field devices using double-shielded STP Category 5e or higher cables. Keep network lines separated from high-voltage motor cables to avoid signal distortion.

Database Channel Configuration

Configure the built-in DB connection function via the onboard EtherNet/IP port to stream SQL queries directly to enterprise database servers without intermediate gateway modules.
