It fits a 120.5 mm wide by 80 mm high by 62 mm deep footprint, designed for DIN-rail mounting in a control cabinet alongside expansion modules. The CPU provides 14 digital inputs (sink/source configurable per group) and 10 digital outputs, with a maximum of 256 I/O points via expansion bus. Six high-speed counters (30 kHz each, 32-bit) handle incremental encoder feedback or up/down counting, and two pulse outputs (Q 0.0, Q 0.1) switch at up to 2 µs rise time for stepper or servo pulse trains. ## Supply range, program retention, and backup The 24 V DC supply accepts 15.4 to 28.8 V, drawing 7 W typical. Program and DB1 data reside on integral EEPROM — no battery needed for program retention. Current values of DB1, retentive memory bits, timers, and counters are buffered by a high-performance capacitor (190 h backup at 40 °C, 120 h minimum). An optional battery module extends backup to 200 days typical. The CPU supports three programming languages: LAD (ladder), FBD (function block diagram), and STL (statement list), selectable per project in the Siemens STEP 7-Micro/WIN environment. The instruction set covers bit logic, timers (1 ms to 54 min range), counters, integer and floating-point math, shift/rotate, table, and communications instructions. ## Communications and high-speed I/O An integrated RS 485 interface supports PPI protocol (9.6/19.2/187.5 kbit/s) for programming, HMI panels (TD 200, OP), and CPU-to-CPU communication. MPI slave mode enables data exchange with S7-300/S7-400 CPUs, OPs, and TDs at 19.2/187.5 kbit/s. Shielded cable runs up to 150 m; unshielded also 150 m. Six high-speed counters (30 kHz each) are parameterizable on inputs E 0.0 to E 1.5, with enable/reset inputs and interrupt-on-setpoint capability. Two of these counters can be configured as A/B quadrature encoder inputs at up to 20 kHz. The 10 digital outputs switch standard loads with a 15 µs rise time (Q 0.2 to Q 1.1) and 100 µs fall time; pulse outputs Q 0.0 and Q 0.1 switch in 2 µs rise and 10 µs fall.","metaTitle":"Siemens 6ES7214-1AD22-0XB0 S7-200 CPU 224 DC/DC/DC PLC","metaDescription":"Siemens S7-200 CPU 224 DC/DC/DC PLC, 14 inputs/10 outputs, 24 V DC supply, 256 I/O expansion, 6 high-speed counters, 30 kHz parameterizable inputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"FBD":"Yes","LAD":"Yes","MPI":"Yes; As MPI slave for data exchange with MPI masters (S7-300/S7-400 CPUs, OPs, TDs, Push Button Panels); S7-200-internal CPU/CPU communication is possible in the MPI network with restrictions; transmission rates: 19.2/187.5 kbit/s","PPI":"Yes; with PPI protocol for program functions, HMI functions (TD 200, OP), S7-200-internal CPU/CPU communication ; transmission rates 9.6/19.2/187.5 kbit/s","STL":"Yes","24 V":"Yes; permissible range: 15.4 to 28.8 V","Depth":"62 mm","Width":"120.5 mm","Height":"80 mm","Number":"256","24 V DC":"Yes","Present":"Yes; Program: Entire program maintenance-free on integral EEPROM, programmable via CPU; data: Entire DB 1 loaded from PG/PC maintenance-free on integral EEPROM, current values of DB 1 in RAM, retentive memory bits, timers, counters, etc. maintenance-free via high-performance capacitor; optional battery for long-term buffering","Adjustable":"Yes; via high-performance capacitor or battery","Command set":"Bit logic instructions, compare instructions, timer instructions, counter instructions, clock instructions, transmissions instructions, table instructions, logic instructions, shift and rotate instructions, conversion instructions, program control instructions, interrupt and communications instructions, logic stack instructions, integer maths, floating-point math instructions, numerical functions","Lower Limit":"1 ms","Upper Limit":"54 min; 4 timers: 1 ms to 30 s; 16 timers: 10 ms to 5 min; 236 timers: 100 ms to 54 min","For Uprating":"Yes","Number, max.":"32 byte","2-Wire Sensor":"Yes","For Signal \"0\"":"0 to 5 V","For Signal \"1\"":"min. 15 V","Interface type":"Integrated RS 485 interface","Shielded, Max.":"150 m","Operation, max.":"95 %; RH class 2 in accordance with IEC 1131-2","Operation, min.":"5 %","Parameterizable":"Yes; (E 0.0 to E 1.5) 30 kHz","Weight, approx.":"360 g","lifecycle_stage":"current","\"0\" To \"1\", Max.":"15 µs; of the standard outputs, max.
