Description

The 3500/92 Communication Gateway module provides extensive

communication capabilities ofallrack monitored values and statuses

for integration with process control and other automation systems

using both EthernetTCP/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 (viaserialcommunications)

• Modbus/TCPprotocol (a variant of serial Modbus used for

TCP/IP Ethernet communications)

• Proprietary Bently Nevadaprotocol (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 theprimary value Modbus

registers.
