3500/92-01-01-00 Bently Nevada Communication Gateway Module

3500/92 Communication Gateway

Description The 3500/92 Communication Gateway module provides extensive communication capabilities for all rack-monitored values and statuses. It integrates 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 Ethernet communications)
• Proprietary Bently Nevada protocol (for communication with 3500 Rack Configuration and Data Acquisition Software packages)

The 3500/92 supports the communication interfaces, protocols, and other features from the original 3500/90, with the exception of the primary value Modbus registers. The 3500/92 now includes a Configurable Modbus Register Utility, providing the same functionality originally addressed by the primary value Modbus registers.

Specifications

Inputs

• Power Consumption:
  • 5.0 watts typical with Modbus RS232/RS422 I/O Module
  • 5.6 watts typical with Modbus RS485 I/O Module
• Data Types: Collects data from other modules in the rack, such as current measured values with timestamp, module statuses, and current alarm statuses, via a high-speed internal network. Exact data types returned depend on module type and channel configuration.
• Update Time: Data collection rate depends on rack configuration but will not exceed 1 second for all modules in the 3500 rack.

Outputs

• OK LED: Indicates when the 3500/92 is operating properly.
• TX/RX LED: Indicates when the 3500/92 is communicating with other modules in the 3500 rack.

Protocols

• BNC Host Protocol: Communication with 3500 Configuration Software and 3500 Data Acquisition and Display Software over Ethernet TCP/IP.
• Modbus: Based on AEG Modicon PI-MBUS-300 Reference Manual. Uses Remote Terminal Unit (RTU) transmission mode.
