The MB3180, MB3280, and MB3480 are standard Modbus gatewaysthat convert between Modbus TCP and Modbus RTU/ASCII protocols. Upto 16 simultaneous Modbus TCP masters are supported, with up to 31RTU/ASCII slaves per serial port. For RTU/ASCII masters, up to 32TCP slaves are supported. Routing through the serial ports can becontrolled by IP address, TCP port number, or ID mapping. Serial-portrouting by TCP port and IP address allows access for up to 4 TCP clients/masters(MB3280/MB3480 models), while routing by ID mapping allows accessfor up to 16 TCP clients/masters (MB3180/MB3280/MB3480).
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 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.
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 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.
Moxa’s Auto-Device Routing function helps eliminate manyof the problems and inconveniences encountered by engineers who needto configure large numbers of Modbus devices. A single mouse clickis all that’s required to set up a slave ID routing table and configureModbus gateways to automatically detect Modbus requests from a supervisorycontrol and data acquisition (SCADA) system. By removing the needto manually create the slave ID routing table, the Auto-Device Routingfunction saves engineers significant time and cost.
