Operating as a dedicated Snet interface, it provides asynchronous serial data exchange between PLC controllers and external industrial field devices, including drives, instrumentation, and supervisory systems.\u003c\/p\u003e\n\u003ch3\u003eChannel Configuration and Communication Performance\u003c\/h3\u003e\n\u003cp\u003eThe module features two independent RS-422 serial channels supporting asynchronous communication at transmission speeds from 300 bps to 115,200 bps. It accommodates point-to-point (1:1), multidrop (1:N), and multi-master (N:M) network topologies across distances up to 500 meters. Up to 32 stations (station numbers 0-31) can be addressed across the network segment.\u003c\/p\u003e\n\u003ch3\u003eProtocol Support and System Diagnostics\u003c\/h3\u003e\n\u003cp\u003eProgrammable via SoftMaster-NM software, the 2MLL-C42B supports Modbus RTU\/ASCII, peer-to-peer (P2P), and user-defined custom protocols. Data framing options include selectable data bits (7 or 8), stop bits (1 or 2), and parity checking (odd, even, or none). Front-panel LEDs for RUN, I\/F, TX, RX, and ERR deliver real-time diagnostic status alongside integrated loopback and frame monitoring functions.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003e2MLL-C42B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eMasterLogic-200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eSerial Communication Module (Snet Interface)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Interface\u003c\/td\u003e\n\u003ctd\u003eRS-422\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Mode\u003c\/td\u003e\n\u003ctd\u003eAsynchronous Serial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBaud Rate\u003c\/td\u003e\n\u003ctd\u003e300 to 115,200 bps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Distance\u003c\/td\u003e\n\u003ctd\u003e500 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Topology\u003c\/td\u003e\n\u003ctd\u003e1:1, 1:N, N:M\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Stations\u003c\/td\u003e\n\u003ctd\u003e32 (Station range: 0-31)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Protocols\u003c\/td\u003e\n\u003ctd\u003eModbus RTU, Modbus ASCII, P2P, User-Defined\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Framing\u003c\/td\u003e\n\u003ctd\u003e7\/8 Data Bits, 1\/2 Stop Bits, Odd\/Even\/None Parity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration Software\u003c\/td\u003e\n\u003ctd\u003eSoftMaster-NM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus Indicators\u003c\/td\u003e\n\u003ctd\u003eRUN, I\/F, TX, RX, ERR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRack Installation\u003c\/td\u003e\n\u003ctd\u003eMasterLogic-200 PLC Rack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary function of the 2MLL-C42B module in a MasterLogic-200 system?
