This high-performance hardware processor handles high I\/O density scaling and massive data structures with deterministic execution cycle times. It coordinates with the redundant peer CPU using dedicated synchronization links. The unit enforces absolute data alignment and cycle parity across the inter-processor connection. This ensures synchronized firmware flash compatibility and immediate bit-stream tracking during high-availability automation processes connected via PROFIBUS DP or Industrial Ethernet nodes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What function does the \"R\" suffix on this CPU 948R designate?\u003c\/p\u003e\n\u003cp\u003eA: The \"R\" designates built-in redundancy hardware support, featuring onboard synchronization interfaces required to run a hot-standby pair within the fault-tolerant S5-155H architecture.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 1600 KB RAM internal memory be expanded further?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
