Moxa MGate MB3280 Modbus TCP Gateway

Introduction

Moxa MGate MB3280 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

Moxa MGate MB3280 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 Moxa MGate MB3280 offer features that make network integration easy, customizable, and compatible with almost any Modbus network.

High Density, Cost-Effective Gateways

The Moxa MGate MB3280 gateways can effectively connect a high density of Modbus nodes to the same network. The Moxa MGate MB3280 can manage up to 62 serial slave nodes, and the MB3480 can manage up to 124 serial slave nodes. Each RS-232/422/485 serial port can be configured individually for Modbus RTU or Modbus ASCII operation and for different baudrates, allowing both types of networks to be integrated with Modbus TCP through one Modbus gateway.
