Bently Nevada 3500/92-02-01-00 136180-01 Communication

This communication gateway module serves as the primary data interface for Bently Nevada 3500 machinery protection systems. It collects monitored values, alarms, and statuses from the rack backplane and transmits them to external networks. The module bridges the 3500 system with plant-wide control and monitoring infrastructures.

Gateway Function and Protocol Support

The Bently Nevada 3500/92-02-01-00 136180-01 supports both Modbus RTU over serial (RS232/RS422/RS485) and Modbus/TCP over Ethernet . It also uses the proprietary Bently Nevada protocol for communication with 3500 Rack Configuration and Data Acquisition Software . The module delivers real-time data, including vibration measurements, temperature readings, setpoints, and alarm statuses, to higher-level systems . Configurable Modbus registers allow users to map critical values to consecutive addresses for efficient data polling .
