CI857K01 3BSE018144R1故障检测-该软件定期检测外部环境，如电源故障、欠压、锂电池电压低和强干扰信号。以便及时处理。信息保护和恢复-当偶尔出现故障时，PLC内部的信息不会被破坏。一旦故障条件消失，它可以恢复正常并继续原来的程序操作。CI857K01 3BSE018144R1因此，当PLC检测到故障状态时，它会立即将当前状态存储在存储器中，软件会配合密封存储器，禁止对存储器进行任何操作，以防止存储的信息被刷新。设置看门狗WDT（看门狗）-如果程序每个周期的执行时间超过WDT指定的时间，则表示程序进入无限循环并立即报警。加强对程序的检查和验证——一旦程序出错，将立即报警并停止执行。CI857K01 3BSE018144R1

Fault detection – The software regularly detects the external environment, such as power failure, undervoltage, low lithium battery voltage and strong interference signals. for timely processing.     CI857K01 3BSE018144R1

Information protection and recovery – when the occasional fault condition occurs, the information inside the PLC will not be destroyed. Once the fault condition disappears, it can return to normal and continue the original program operation. Therefore, when the PLC detects a fault condition, it immediately stores the current state in the memory, and the software cooperates to seal the memory, prohibiting any operation on the memory to prevent the stored information from being flushed.

Set the watchdog WDT (watchdog) – If the execution time of each cycle of the program exceeds the time specified by the WDT, it indicates that the program enters an infinite loop and immediately alarms.          Strengthen the inspection and verification of the program – once the program is wrong, it will immediately alarm and stop the execution.
