As an internal communication daughtercard, this module integrates directly onto the host processor's main circuit board, providing deterministic, token-passing ControlNet network connectivity for non-redundant media architectures. It is ideal for mid-range automation applications, including localized assembly stations, food and beverage processing, and industrial pump skids.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Integration:\u003c\/strong\u003e Mounts directly to the internal communication interface headers of the FlexLogix controller, utilizing high-speed system buses for low-latency data transfer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetwork Capacity:\u003c\/strong\u003e Supports up to 32 concurrent scheduled or unscheduled network connections for seamless remote I\/O management and peer-to-peer messaging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControlNet Connectivity:\u003c\/strong\u003e Operates at a 5 Mbps transmission speed using standard coaxial physical media.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Efficiency:\u003c\/strong\u003e Offloads network communication tasks from the primary CPU execution cycle.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is designed for use in industrial environments requiring robust, deterministic network communication.
