Programming is supported in LAD, FBD, and STL — the full instruction set including bit logic, timers, counters, integer and floating-point maths, and communications instructions. ## Protocols and network integration The integrated RS 485 interface supports both PPI and MPI protocols. PPI handles program functions and HMI communication (TD 200, OP) at 9.6/19.2/187.5 kbit/s, plus S7-200-internal CPU/CPU data exchange. MPI allows the CPU to act as a slave for data exchange with S7-300/S7-400 CPUs, OPs, and TDs at 19.2/187.5 kbit/s. Maximum cable length is 500 m shielded, 150 m unshielded — enough for most machine-level networks within a panel or across a small line. ## I/O and high-speed counting The 14 inputs are source/sink configurable per group. Six high-speed counters (30 kHz each, 32-bit) can serve as up/down counters or connect two incremental encoders with 90° offset pulse trains at up to 20 kHz (A/B counters). Parameterizable enable and reset inputs, plus interrupt facilities on setpoint reach. Outputs switch from 0 to 1 in max 15 µs (standard) or 2 µs (pulse outputs Q0.0–Q0.1), and from 1 to 0 in max 130 µs (standard) or 10 µs (pulse outputs). Maximum lamp load is 5 W per output. ## Memory and backup Program storage is maintenance-free on integral EEPROM; DB1 data loads from PG/PC to EEPROM, with current values in RAM. Retentive memory bits, timers, and counters are buffered by a high-performance capacitor (min 70 h at 40 °C, typ 100 h). An optional battery module extends backup to 200 days typical. The retentive memory size is adjustable up to 32 bytes. Timers span 1 ms to 54 min across 256 timers (4 at 1 ms–30 s, 16 at 10 ms–5 min, 236 at 100 ms–54 min).","metaTitle":"Siemens 6ES7214-1AD23-0XB0 S7-200 CPU 224 DC, 14 I/O","metaDescription":"Siemens 6ES7214-1AD23-0XB0 S7-200 CPU 224 DC PLC. 14 inputs/10 outputs, 24 V DC supply.
