Installed directly into a modular CPU baseplate slot, the module processes multi-point serial communications across independent RS-232 and RS-485 interfaces via SNP, CCM, and Modbus RTU Slave protocols without increasing CPU scan cycle times.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\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\u003c\/td\u003e\n\u003ctd\u003eIC693CMM311N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Fanuc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.90 lbs (0.41 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Series 90-30 Single-Slot Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C (32 to 140 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e400 mA @ +5 VDC (Backplane Bus)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSerial Interfaces\u003c\/td\u003e\n\u003ctd\u003ePort 1: Dedicated RS-232 \/ Port 2: Selectable RS-232 or RS-485\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Protocols\u003c\/td\u003e\n\u003ctd\u003eSNP, CCM, Modbus RTU (Slave)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 4 modules per system (CPU 331 or higher)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCPU Compatibility\u003c\/td\u003e\n\u003ctd\u003eModular CPUs (311, 313, 323, 331 and higher)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFirmware Version\u003c\/td\u003e\n\u003ctd\u003eVersion 4.0 or higher\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Category\u003c\/td\u003e\n\u003ctd\u003ePLCs\/Machine Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSub-Category\u003c\/td\u003e\n\u003ctd\u003eCommunication Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity \u0026amp; I\/O Density Scaling\u003c\/h3\u003e\n\u003cp\u003eInterfacing directly with the Series 90-30 logic backplane, the IC693CMM311N maintains backplane bus communication velocity by executing serial message framing, checksum verification, and protocol handshakes asynchronously. Dual independent serial ports enable simultaneous multi-drop and point-to-point topologies across expanded rack setups. Internal optical isolation barriers protect internal backplane traces from ground loop currents and transient voltage surges on serial field loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the IC693CMM311N compatible with Series 90-30 embedded CPU baseplates?\u003c\/p\u003e\n\u003cp\u003eA: No. The module requires a modular CPU architecture (such as CPU 311, 313, 323, or 331) and does not support embedded CPU units (such as CPU 311E or 313E).\u003c\/p\u003e\n\u003cp\u003eQ: Can both serial ports on the IC693CMM311N operate simultaneously on Modbus RTU?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
