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
that convert between Modbus TCP and Modbus RTU/ASCII protocols.
Up to 16 simultaneous Modbus TCP masters are supported, with up to
The three standard MGate™ models (MB3180, MB3280, and MB3480)
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
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
The MGate™ MB3000 gateways can effectively connect a high density
of Modbus nodes to the same network. The 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
of Modbus nodes to the same network. The 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
31 RTU/ASCII slaves per serial port. For RTU/ASCII masters, up to 32
TCP slaves are supported.
TCP slaves are supported.
Modbus TCP slaves can be made accessible to serial masters. The
MB3180, MB3280, and MB3480 offer features that make network
integration easy, customizable, and compatible with almost any
Modbus network.
