Operating at a high-speed data transfer rate of 5 Mbps, the unit provides reliable determinism for time-critical industrial control networks. It supports up to 32 logical connections, enabling real-time I\/O control, peer-to-peer messaging, and program maintenance across complex automation systems.\u003c\/p\u003e\n\u003ch3\u003eMedia Redundancy and Network Architecture\u003c\/h3\u003e\n\u003cp\u003eEquipped with dual coaxial BNC connectors, the \u003cstrong\u003e1788-CNCR\u003c\/strong\u003e supports redundant network cabling configurations to ensure continuous operational uptime. If a break or fault occurs on the primary coaxial link, data transmission automatically switches over to the secondary line without interrupting process operations or faulting the connected controller. This deterministic architecture makes it suitable for critical machine control and distributed process environments.\u003c\/p\u003e\n\u003ch3\u003eSystem Integration and Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis module connects directly to the system backbone of FlexLogix (1794-L3x) controllers and compatible DriveLogix processor platforms, allowing seamless integration of local and remote ControlNet drops. Maintenance personnel and system integrators can configure network parameters, target nodes, and connection schedules using RSNetWorx for ControlNet software.\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\u003c\/td\u003e\n\u003ctd\u003e1788-CNCR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eCommunication Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork\u003c\/td\u003e\n\u003ctd\u003eControlNet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMedia Type\u003c\/td\u003e\n\u003ctd\u003eRedundant Coaxial (BNC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBaud Rate\u003c\/td\u003e\n\u003ctd\u003e5 Mbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Connections\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Controllers\u003c\/td\u003e\n\u003ctd\u003eFlexLogix \/ DriveLogix Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.42 lbs (0.19 kg)\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 main difference between the 1788-CNC and the 1788-CNCR?
