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:
Modicon® Modbus® protocol (via serial communications)
Modbus/TCP protocol (a variant of serial Modbus used for TCP/IP
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.
