It supports three IEC programming languages: FBD (Function Block Diagram), LAD (Ladder Diagram), and STL (Statement List). ## Onboard communications and connectivity A single integrated RS 485 port (unshielded max 150 m, shielded max 500 m) handles both MPI and PPI protocols. MPI operates as a slave at 19.2 or 187.5 kbit/s; PPI supports program functions, HMI, and CPU-to-CPU communication at 9.6, 19.2, or 187.5 kbit/s. ## Power, backup, and physical footprint Typical power loss is 11 W. The CPU includes a retentive memory backup via high-performance capacitor: minimum 70 h at 40 °C, up to 100 h max; adding an optional battery module extends to 200 days typical. The housing measures 196 mm wide × 80 mm high × 62 mm deep.","metaTitle":"Siemens 6AG1216-2AD23-2XB0 S7-200 CPU, 24V DC","metaDescription":"Siemens 6AG1216-2AD23-2XB0 S7-200 CPU 224XP compact controller, 24 V DC, supports FBD/LAD/STL, MPI/PPI.
