Bently Nevada 3500-92 136188-01 is a communication gateway module in Bently Nevada’s 3500 series machinery protection and condition monitoring system.The following are its product details:
I.Core functions
Communication capabilities
Protocol support:Supports Modicon Modbus protocol(via serial port communication),Modbus/TCP protocol(TCP/IP Ethernet communication variant of serial Modbus application)and proprietary Bently Nevada communication protocol for Ethernet communication and data acquisition with 3500 framework configuration software.
Interface type:Provides Ethernet TCP/IP and serial(RS232/RS422/RS485)communication interfaces,which can be integrated with process control and other automation systems to achieve data interaction with other control systems or devices.
Data processing and conversion
Modbus register configuration:Has a configurable Modbus registry utility,providing the same functions as the original 3500/90 module,communicating through Modbus registers.Users can configure parameters according to actual needs,such as setting communication baud rate,data bit,stop bit,parity bit,etc.,to adapt to different communication environments and equipment requirements.
Data format conversion:Process and convert the data collected by each monitoring module of the 3500 system,convert the original data into data that conforms to a specific protocol and format,which is convenient for other systems to read and understand,and can also package and compress the data to improve data transmission efficiency.
System integration and expansion
System integration:As a bridge between the 3500 system and external systems,the 3500 system can be seamlessly integrated with other automation systems in the factory to achieve information sharing and collaborative work,which helps to improve the automation level and production efficiency of the entire factory.For example,the operating status data of the unit is transmitted to the DCS system so that the operator can uniformly monitor and manage the entire production process in the central control room.
Scalability:It is convenient to expand the 3500 system,and more monitoring modules or external devices can be connected to meet monitoring needs of different scales and complexities.When expanding a plant or upgrading equipment,by adding new monitoring modules and using the 3500-92 136188-01 communication gateway module,the data of the new modules can be incorporated into the existing monitoring system.
