Communication frames are transmitted over 100BASE-TX links with deterministic arbitration to maintain synchronization between duplex CPUs and remote safety nodes.\u003c\/p\u003e\n\u003cp\u003eChannel-to-channel isolation is enforced at both processor and backplane levels, preventing cross-interference between redundant execution paths during safety logic evaluation cycles. Memory protection logic preserves last-valid state retention during brownout or full power loss events.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the SSC50D-F2524 operate in hot-swap CPU replacement mode?\u003c\/strong\u003e\u003cbr\u003eA: CPU module replacement is not hot-swappable.
