Bentley 3500/92 communication gateway module
Description
The 3500/92 Communication Gateway module provides extensive communication capabilities for all rack monitoring values and status for integration with process control and other automation systems using Ethernet TCP/IP and serial (RS232/RS422/RS485) communication capabilities. It also allows Ethernet communication with 3500 rack configuration software and data acquisition software.
Supported protocols include:
·Modbus protocol (via serial communication)
·Modbus/TCP protocol (a variant of serial Modbus for TCP/IP Ethernet communication)
Proprietary Bentley Nevada Protocol (for use with 3500 rack configuration and data acquisition packages)
In addition to the main Modbus register, the 3500/92 supports the original 3500/90 communication interface, communication protocol, and other features. 3500/92 now has a configurable Modbus register utility that provides the same functionality originally handled by the Modbus master value register.
