Power dissipation is 17 W typical — no extra cooling needed in a standard IP20 cabinet. The backup time on the built-in high-performance capacitor is 100 h (70 h at 40 °C), and an optional battery module extends it to 200 days. That matters for MRO: if your line loses power over a weekend, the capacitor keeps the program and retentive data intact. All 6 high-speed counters are 32-bit, bidirectional, and can be configured as up/down counters or connect to incremental encoders with 90° offset pulses at up to 20 kHz (A/B mode). Each counter has parameterizable enable and reset inputs, plus interrupt capability — handy for fast position capture without scanning cycle jitter. ## Field notes for install and swap Dimensions are 196 x 80 x 62 mm (W x H x D), sits on standard DIN rail. All digital outputs switch in max 10 ms (both on and off) — acceptable for most solenoids and contactors, but check if your load needs faster response. The RS485 port handles both MPI (19.2/187.5 kbit/s) and PPI (9.6/19.2/187.5 kbit/s), and you can mix S7-200 CPUs on the same PPI network. Program and data are held in integral EEPROM on the CPU — no battery needed to retain the program; the capacitor or optional battery only covers retentive data.","metaTitle":"Siemens 6ES7216-2BD23-0XB0 S7-200 CPU 226, 24 V DC","metaDescription":"Siemens SIMATIC S7-200 CPU 226, 24 V DC, 6 high-speed counters 30 kHz, MPI/PPI, LAD/FBD/STL.
