Serial Connectivity for Micro-SX Systems

The FUJI NP1L-LE1 communication module provides serial connectivity for Micro-SX programmable controllers. This module handles data exchange with external devices such as HMIs, printers, and barcode readers. Industrial networks require versatile interfaces, and this unit delivers that flexibility effectively.

Communication Specifications and Protocol Support

This communication module features one RS-232C port with a 9-pin D-sub connector for device connectivity. The port supports data rates from 300 bps to 38.4 kbps with software-selectable parameters. An additional RS-485 port enables multi-drop networking with up to 31 stations. Furthermore, the module supports both ASCII and binary data formats for flexible integration.

Data Handling and Buffering

The FUJI NP1L-LE1 incorporates an 8 KB buffer RAM for storing incoming and outgoing messages. This buffer handles burst transmissions without losing data packets. Hardware and software flow control mechanisms prevent buffer overflows. Additionally, the module supports both half-duplex and full-duplex communication modes.

Protocol Support and Configuration

This communication module supports ASCII and MODBUS RTU protocols for device compatibility. Users can configure data bits, stop bits, parity, and baud rate through the programming software. The module automatically detects the connected device’s protocol parameters. Moreover, the module allows custom protocol definition for specialized equipment integration.

Physical Design and Installation

This communication module features a compact 40 mm housing that fits standard Micro-SX racks. The unit weighs approximately 0.18 kilograms, allowing straightforward installation. Front-panel LEDs indicate power, port activity, and error conditions. The module includes DIP switches for setting the station address in multi-drop networks.

Diagnostic Features and Status Monitoring

LED indicators on the front panel show the status of each communication port. The module logs communication errors in a diagnostic buffer for troubleshooting. A built-in loopback test verifies port functionality during system startup. Furthermore, the module provides error counters for monitoring communication quality over time.

System Integration and Application Areas

You can install this communication module in any slot of the Micro-SX central or expansion rack. The module works with various serial devices, including operator panels and weighing scales. For RS-485 multi-drop configurations, terminate both ends of the bus segment. Always use shielded cables for reliable communication in industrial environments.
