Features and Benefits
- Convert between Modbus TCP and Modbus RTU/ASCII
- 1 Ethernet port and 1, 2, or 4 RS-232/422/485 ports
- Supports 16 simultaneous TCP masters with up to 32 simultaneous requests per master
- Easy hardware setup and configuration
Overview
The MB3180, MB3280, and MB3480 are standard Modbus gateways that convert between Modbus TCP and Modbus RTU/ASCII protocols. Up to 16 simultaneous Modbus TCP masters are supported, with up to 31 RTU/ASCII slaves per serial port. For RTU/ASCII masters, up to 32 TCP slaves are supported.
Standard Modbus network integration
MGate MB3000 standard models include the MB3180, MB3280, and MB3480, and are designed for easy integration of Modbus TCP and RTU/ASCII networks. With these models, Modbus serial slave devices can be seamlessly incorporated into an existing Modbus TCP network, and Modbus TCP slaves can be made accessible to serial masters. The MB3180, MB3280, andMB3480 offer features that make network integration easy, customizable, and compatible with almost any Modbus network.
High density, cost effective gateway
The MGate MB3000 can effectively integrate networks with a high density of Modbus nodes. The MB3280 can manage up to 62 serial slave nodes, whereas the MB3480 can manage 124. Each RS-233/422/485 serial port can be individually configured for Modbus RTU or Modbus ASCII operation or even different baudrate, allowing both types of networks to be integrated with Modbus TCP within one package.
