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. Routing through the serial ports can be controlled by IP address, TCP port number, or ID mapping. Serial-port routing by TCP port and IP address allows access for up to 4 TCP clients/masters (MB3280/MB3480 models), while routing by ID mapping allows access for up to 16 TCP clients/masters (MB3180/MB3280/MB3480).
