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 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.
