Bently Nevada 3500/92-04-01-01 Ethernet/RS485 Communication Gateway
A 3500 communication gateway with Ethernet/RS485 Modbus I/O, low-memory option and CSA/NRTL/C approval.
Key Information
3500/92-04-01-01 is a Bently Nevada 3500/92 Communication Gateway configuration. Code 04 selects the Ethernet/RS485 Modbus I/O module, code 01 selects low memory and the final 01 selects CSA/NRTL/C approval.
The gateway collects monitored values, timestamps, module states and alarm states from the 3500 rack and makes selected information available to process-control or automation systems through Ethernet or serial communications.
Functions
- Communicates by Modbus/TCP over 10BASE-T Ethernet.
- Supports Modbus RTU communication through the RS485 I/O interface.
- Exchanges configuration and acquisition data using the Bently Nevada host protocol over Ethernet TCP/IP.
- Collects rack data across the high-speed internal network with an update time not exceeding one second.
- Provides OK and TX/RX front-panel status indication.

Installation
- Reserve one full-height front slot and one full-height rear slot in the 3500 rack.
- Use shielded Category 5 cabling with RJ45 connectors for the 10BASE-T Ethernet connection.
- Engineer the RS485 cable run, termination and host interface for the selected Modbus network.
- Configure the Modbus map and communication parameters in 3500 Rack Configuration Software.
- Check I/O-module firmware compatibility when combining a newer I/O module with an older gateway main board.
Lifecycle
- Retain the full 3500/92-04-01-01 code because the I/O, memory and approval positions define the gateway configuration.
- Back up the Modbus register map, serial settings, IP information and rack configuration before replacement.
- Record the RS485 cable topology and termination arrangement for recommissioning.
- Confirm firmware compatibility when replacing only the gateway I/O module.
- Verify process-control data mapping and alarm/status exchange after service.
