Modbus RTU Data Forwarding

Encapsulates real-time data from various 3500 monitoring modules—including vibration, displacement, temperature, and status information—into standard Modbus RTU format. Data is transmitted to DCS, PLC, or SCADA systems via the RS-485 interface, enabling centralized equipment condition monitoring.

Flexible Parameter Configuration

Supports remote configuration of Modbus slave address, register mapping, communication baud rate, and other parameters through the 3500 system configuration software. This flexibility allows seamless adaptation to different upper-level control and monitoring systems.

Status Diagnostics and Alarm Reporting

Features built-in monitoring of module operating status. Communication faults and abnormal conditions are actively reported as alarm signals, allowing fast identification and troubleshooting of communication link issues.

System Compatibility and Integration

Fully compatible with the 3500/05 rack and designed to operate in conjunction with the 3500/92 Ethernet gateway. Supports multi-protocol communication architectures (Modbus RTU and Ethernet), meeting the requirements of complex system integration and hybrid network environments.

Typical Applications
Power Generation Industry

Uploads operating status and condition monitoring data of rotating equipment such as steam turbines, generators, and feedwater pumps to the plant DCS, supporting equipment protection, fault diagnosis, and predictive maintenance.

Petrochemical Industry

Integrates vibration and process monitoring data from critical rotating machinery including compressors, pumps, and fans, ensuring safe operation and continuous production.

Metallurgical Industry

Enables remote transmission of vibration and displacement data from rolling mill main motors, gearboxes, and auxiliary equipment, suitable for harsh environments with high temperatures and heavy dust.

Legacy System Upgrade

Expands RS-485 communication capability of existing 3500 systems. Maintains compatibility with legacy Modbus RTU-based upper-level systems, minimizing upgrade costs while improving data accessibility.
