The module includes 30 KB of program/data memory and is designed for small automation tasks, with a power supply specification listed as 85-264 V AC at 47-63 Hz. This specific part is no longer available, with the successor 6ES7211-1BE40-0XB0 noted as partly compatible. Typical applications include basic machine control and small-scale PLC projects that require S7-1200 compatibility.
