S7G2 IEC 61508 自检库

AI 生成的摘要: IEC 61508 defines safety integrity levels (SIL) for electrical and electronic safety systems, with SIL4 being the highest risk level. Safety systems rely on microcontrollers (MCUs) that must verify correct operation of critical functions. The S7G2 MCU series supports safety applications by providing hardware and software mechanisms to detect and handle faults. Key modules include watchdog timers, voltage detection, communication interfaces, memory protection, and analog/digital converters. The document details recommended settings, safety mechanisms at chip, module, software, and system levels, and common terminology to ensure compliance with IEC 61508 requirements.
