Retention runs on a high-performance capacitor as standard, backed by an optional battery module — the spec puts backup time at 100 h minimum (≥ 70 h at 40 °C) on the capacitor and around 200 days typical with the battery, which is the figure to write into the handover sheet so the maintenance crew knows when DB1 data and retentive bits will start to drift if the battery is missed. ## Inputs, outputs and the high-speed edge Source/sink selection is per group, which lets the wireman follow the cabinet drawing's existing convention rather than re-terminate for a fixed polarity. ## Comms, lengths and the wiring practice The onboard port is an integrated RS-485, usable as an MPI slave for data exchange with S7-300/S7-400 CPUs, OPs, TDs and Push Button Panels at 19.2 or 187.5 kbit/s, and as PPI for program functions, HMI functions (TD 200, OP) and S7-200-internal CPU-to-CPU traffic at 9.6, 19.2 or 187.5 kbit/s. Cable runs follow the usual S7-200 rules: shielded segment up to 500 m at the lower PPI/MPI rates, unshielded segment up to 150 m — these are the limits to write on the cable schedule, not the generic Cat-5 numbers. Program execution is free-cycle OB 1 with time-controlled interrupt at 1 to 255 ms, and the timer stack covers 1 ms to 54 min (with 4 fast timers at 1 ms to 30 s, 16 timers at 10 ms to 5 min and the remainder at 100 ms to 54 min), which matches the standard S7-200 instruction set the existing code is likely written against.","metaTitle":"Siemens 6ES7214-2AD23-0XB0 CPU 224, 24 VDC, MPI/PPI","metaDescription":"Siemens SIMATIC S7-200 CPU 224 (6ES7214-2AD23-0XB0): 24 VDC supply, 14 DI/10 DO, MPI + PPI onboard, FBD/LAD/STL, lifecycle current.
