3500/92 Communication Gateway
Datasheet

Bently Nevada Machinery Condition Monitoring141542 Rev. M

Description
The 3500/92 Communication Gateway module provides
extensive communication capabilities of all rack monitored
values and statuses for integration with process control andother automation systems using both Ethernet TCP/IP andserial (RS232/RS422/RS485) communications capabilities. It
also permits Ethernet communications with 3500 Rack
Configuration Software and Data Acquisition Software.
Supported protocols include:lll

Modicon Modbus protocol (via serial communications)Modbus/TCP protocol (a variant of serial Modbus usedfor TCP/IP Ethernet communications)
Proprietary Bently Nevada protocol (for communication
with 3500 Rack Configuration and Data Acquisition
Software packages)
The Ethernet connection to the 3500/92 is an RJ45
connection for 10BASE-T star configuration Ethernet
networks.

The 3500/92 supports the communication interfaces,
communication protocols, and other features from theoriginal 3500/90 with the exception of the primary value
Modbus registers. The 3500/92 now has a Configurable
Modbus Register Utility, which can provide the samefunctionality originally addressed by the primary value
Modbus registers.
