MGate MB3480 MOXA Gateways

Features and Benefits

• Convert between Modbus TCP and Modbus RTU/ASCII
• 1 Ethernet port and 2 RS-232/422/485 ports
• 16 simultaneous TCP masters with up to 32 simultaneous requests per master
• Easy hardware setup and configuration

Introduction

The MGate MB3480 is standard Modbus gateway 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. Moxa MB3480 is designed for easy integration of Modbus TCP and RTU/ASCII networks. With this model, 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. Moxa Mgate MB3480 offers features that make network integration easy, customizable, and compatible with almost any Modbus network. The MGate™ MB3000 gateways can effectively connect a high density of Modbus nodes to the same network. The Moxa MGate 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.
