Fuji NP1L-RM1 Bit Level Communication Module

Simple I/O Data Exchange Between PLCs

This communication module enables bit-level data sharing between multiple controllers. The Fuji NP1L-RM1 exchanges I/O status with up to 16 slave stations on a network. It transfers input and output bits automatically without programming overhead. A dedicated communication processor handles all network traffic independently. Consequently, this module simplifies coordination between machines on a production line.

Network Specifications & Data Capacity

The Fuji NP1L-RM1 uses a high-speed RS-485 network for deterministic data exchange. You can connect this master module to multiple slave units across your facility. The network updates all I/O data within a fixed scan cycle. A built‑in LED indicates normal communication and error status. Therefore, this module suits conveyor systems, assembly lines, and material handling applications.

Installation & Network Configuration

You insert the Fuji NP1L-RM1 into any available slot of your MICREX-SX rack. Connect the RS-485 network cable to the 9-pin D-sub connector. Set each slave station address using configuration software. The master module automatically scans all connected slaves after power-up. Your ladder program reads and writes I/O bits from dedicated memory areas.

Operational Advantages & Simplified Coordination

The Fuji NP1L-RM1 eliminates complex programming for data exchange between PLCs. You can share start/stop commands, ready signals, and fault bits easily. The fixed scan cycle ensures predictable response times for interlocked machines. A LINK LED illuminates when all slave stations communicate properly. Therefore, this bit-level module reduces engineering time for multi-PLC systems.
