Network Communication Capabilities
The NP1L-RJ1 link module establishes reliable serial communication between MICREX-SX PLCs and remote field devices. This unit uses an RS-485 interface in 2-wire, half-duplex mode to support both Fuji SX Bus and Modbus RTU protocols. Users can select baud rates from 9600 bps up to 115.2 kbps, enabling optimization for various cable lengths and network sizes. Moreover, the module supports up to 32 nodes per network segment, providing scalable connectivity for distributed automation architectures.
Data Exchange and Scan Performance
Each scan cycle on the NP1L-RJ1 exchanges 128 bytes of input data and 128 bytes of output data between the PLC and connected devices. This capacity accommodates typical field data requirements, including digital I/O statuses, analog values, and parameter settings. The module operates in a polling-based master-slave mode, where the PLC initiates all communication requests. Consequently, this deterministic approach ensures predictable network timing and reliable data delivery.
Physical Installation
Weighing only 0.20 kg and measuring 100 mm x 60 mm x 95 mm, the NP1L-RJ1 occupies minimal space within the control cabinet. This module draws 150 mA from the 5 VDC backplane supply, consuming just 2.0 W of power. Install the unit directly into any available slot in the MICREX-SX SPH rack system. The module automatically configures its network parameters upon initial power-up, reducing setup time and simplifying commissioning.
Diagnostics and Status Indication
The NP1L-RJ1 includes LED indicators that display link status, communication activity, and error conditions. Users can monitor network health through dedicated diagnostic bits accessible from the PLC program. The module also logs communication errors and provides detailed status information via the programming software.
