Description

Description
The 3500/92 Communication Gateway module provides
extensive communication capabilities of all rack monitored
values and statuses for integration with process control and
other automation systems using both Ethernet TCP/IP and
serial (RS232/RS422/RS485) communications capabilities. It
also permits Ethernet communications with 3500 Rack
Configuration Software and Data Acquisition Software.
Supported protocols include:
l Modicon Modbus protocol (via serial communications)
l Modbus/TCP protocol (a variant of serial Modbus used
for TCP/IP Ethernet communications)
l 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 the
original 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 same
functionality originally addressed by the primary value
Modbus registers.
