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 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 31 RTU/ASCII slaves per serial port. For RTU/ASCII masters, up to 32 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. 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. › ›Convert between Modbus TCP and Modbus RTU/ASCII › ›1 Ethernet port and 1, 2, or 4 RS-232/422/485 ports › ›16 simultaneous TCP masters with up to 32 simultaneous requests per master › ›Easy hardware setup and configuration Ethernet Interface Protocols: Modbus TCP Number of Ports: 1 Speed: 10/100 Mbps, Auto MDI/MDIX Connector: 8-pin RJ45 Magnetic Isolation Protection: 1.5 kV (built-in) Serial Interface Protocol: Modbus RTU/ASCII Slave/Master Number of Ports: MB3180: 1 MB3280: 2 MB3480: 4 Serial Standards: RS-232/422/485, software selectable Connectors: DB9 male ESD Protection: 15 kV for all signals RS-485 Data Direction Control: ADDC® (automatic data direction control) Serial Communication Parameters Data Bits: 7, 8 Stop Bits: 1, 2 Parity: None, Even, Odd, Space, Mark Flow Control: RTS/CTS, DTR/DSR, RTS Toggle (RS-232 only) Baudrate: 50 bps to 921.6 kbps Serial Signals RS-232: TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND RS-422: Tx+, Tx-, Rx+, Rx-, GND RS-485-4w: Tx+, Tx-, Rx+, Rx-, GND RS-485-2w: Data+, Data-, GND Software Configuration Options: Web Console, Serial Console, Telnet Console, Windows Utility Utility: MGate Manager for Windows 2000, Windows XP, Server 2003, Vista, Server 2008 (x86/x64), Windows Server 2008 R2, Windows 7/8/8.1 (x86/x64), Windows Server 2012 (x64), Windows 2012 R2 Multi-master and Multi-drop: Master mode: 32 TCP slaves Slave mode: 16 TCP masters (request queue 32-deep for each master) Support: Smart Routing, MXview, SNMP v1 (read only) Physical Characteristics Housing: Metal, IP30 Weight: MGate MB3180: 340 g (0.75 lb) MGate MB3280: 360 g (0.79 lb) MGate MB3480: 740 g (1.63 lb) Dimensions: Without ears: MB3180: 22 x 52 x 80 mm (0.87 x 2.05 x 3.15 in) MB3280: 22 x 77 x 111 mm (0.87 x 3.03 x 4.37 in) MB3480: 35.5 x 102.7 x 157.2 mm (1.40 x 4.04 x 6.19 in)
