Typical power loss is 10 W. The digital inputs are source/sink configurable per group; the outputs switch on lamp loads up to 200 W AC or 30 W DC. Total current drawn from the CPU's 24 V sensor supply is rated. Six high-speed counters (30 kHz each, 32-bit with sign) can handle incremental encoder feedback or count events directly without an add-on module. Backup time from the internal capacitor is 190 hours at 40 °C; an optional battery extends that to 200 days. ## Communication and Programming The integrated RS485 interface supports PPI (for programming and HMI) and MPI protocol; shielded cable runs up to 500 m, unshielded up to 150 m. Programming in LAD, FBD, or STL with free-cycle, interrupt, or time-controlled processing (1–255 ms).","metaTitle":"Siemens 6ES7214-1BD22-0XB0 S7-200 CPU 224XP, RS485 MPI/PPI,","metaDescription":"Active-production Siemens S7-200 CPU 224XP with integrated RS485 MPI/PPI, 24 V DC supply, 6 high-speed counters 30 kHz.
