Full hardware availability requires population of three distinct 3003 modules within the processor chassis slots. Each unit executes safety applications in parallel, continuously sharing memory data and logic calculations across the TriBus backplane. The architecture relies on absolute 2oo3 hardware voting mechanisms to resolve processing states before updating output cards. Internal memory errors are handled automatically by 128 MB Error-Correcting Code (ECC) RAM arrays, which identify and fix single-bit disruptions inline without altering scan schedules.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the primary rules for replacing an active main processor using the online hot-swap capabilities?\u003c\/p\u003e\n\u003cp\u003eA: Online hot-swap requires that the remaining two main processor modules are running in a healthy, synchronized TMR state. Inserting the new module starts an automated synchronization sequence across the TriBus backplane, flashing the active runtime program and internal variables to the replacement core without stopping logic execution.\u003c\/p\u003e\n\u003cp\u003eQ: How does the system handle a continuous logic scan time mismatch between the three independent cores?\u003c\/p\u003e\n\u003cp\u003eA: The TriBus protocol forces lock-step synchronization at the start of every I\/O scan loop. If one core experiences a performance delay that pushes the logic scan time past the 50 ms window, the remaining two modules flag the out-of-sync leg as faulted, record the discrepancy in the system log, and maintain safety loops using 2oo2 degraded voting.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull TMR Slot Population\u003c\/strong\u003e: Install exactly three identical 3003 modules into the assigned processor chassis slots.
