![]() ![]() Once activated, the gateway will learn and remember the Modbus commands it receives, and once a command has been learned, the gateway will act as though it were in agent mode, and actively send Modbus requests to the relevant Modbus devices. In order to provide better performance, the MGate MB3660 gateways are designed with an innovative Command Learning function, which can be activated with a single mouse click. However, since only one Modbus protocol request-response action can be executed at any given time, each Modbus device has to wait its turn, resulting in poorer performance. For transparent mode, the gateway converts Modbus commands from Modbus TCP to Modbus RTU/ASCII, and vice versa, or from serial (master) to serial (slave). The MGate MB3660 gateways support two communication modes: transparent mode and agent mode. High Performance with Innovative Command Learning 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. MODBUS SERVER TCP SERIAL MOXA SERIESThe MB3660 Series can physically manage up to 248 serial slave nodes for 8-port models or 496 serial slave nodes for 16-port models (the Modbus standard only defines Modbus IDs from 1 to 247). The MGate MB3660 gateways offer features that make network integration easy, customizable, and compatible with almost any Modbus network.įor large-scale Modbus deployments, MGate MB3660 gateways can effectively connect a large number of Modbus nodes to the same network. The MGate MB3660 gateways are designed to easily integrate Modbus TCP and RTU/ASCII networks. The MGate MB3660 isolation model provides 2 kV isolation protection suitable for power substation applications. They can be accessed by up to 256 TCP master/client devices, or connect to 128 TCP slave/server devices. Please contact Moxa if you require products guaranteed to function properly at higher altitudes.The MGate MB3660 (MB3660-8 and MB3660-16) gateways are redundant Modbus gateways that convert between the Modbus TCP and Modbus RTU/ASCII protocols. 10/100BaseTX (RJ45) or 100BaseFX (single mode or multi-mode with SC/ST connector) Emergency request tunnels ensure QoS control. ![]() Built-in Ethernet cascading for easy wiring. Up to 2000 m (795 hPa), higher altitudes on demand Accessed by up to 32 Modbus TCP clients (retains 32 Modbus requests for each Master) Supports Modbus serial master to Modbus serial slave communications. Smart Routing, MXview, SNMP v1 (read only) moxa-mgate-mb3170-mb3270-series-datasheet-v1.2. Slave mode: 16 TCP masters (request queue 32-deep for each master) MODBUS SERVER TCP SERIAL MOXA WINDOWSWeb Console, Serial Console, Telnet Console, Windows Utility The MB3280 can manage up to 62 serial slave nodes, and the MB3480 can manage up to 124 serial slave nodes. The MGate™ MB3000 gateways can effectively connect a high density of Modbus nodes to the same network. The MB3180, MB3280, and MB3480 offer features that make network integration easy, customizable, and compatible with almost any Modbus network. 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 three standard MGate™ models (MB3180, MB3280, and MB3480) are designed for easy integration of Modbus TCP and RTU/ASCII networks. For RTU/ASCII masters, up to 32 TCP slaves are supported. ![]() Up to 16 simultaneous Modbus TCP masters are supported, with up to 31 RTU/ASCII slaves per serial port. The MB3180, MB3280, and MB3480 are standard Modbus gateways that convert between Modbus TCP and Modbus RTU/ASCII protocols. ![]()
