在codesys v3中将日期和时间从字符串中拆分

PROGRAM Main
VAR
    dateTimeString: STRING := '2022-12-31 23:59:59';
    dateString: STRING(10);
    timeString: STRING(8);
    year: INT;
    month: INT;
    day: INT;
    hour: INT;
    minute: INT;
    second: INT;
END_VAR

dateTimeString := '2022-12-31 23:59:59';

// 提取日期部分
dateString := LEFT(dateTimeString, 10);
year := TO_INT(LEFT(dateString, 4));
month := TO_INT(MID(dateString, 6, 2));
day := TO_INT(RIGHT(dateString, 2));

// 提取时间部分
timeString := RIGHT(dateTimeString, 8);
hour := TO_INT(LEFT(timeString, 2));
minute := TO_INT(MID(timeString, 4, 2));
second := TO_INT(RIGHT(timeString, 2));

// 输出结果
PRINT('Year: ', year);
PRINT('Month: ', month);
PRINT('Day: ', day);
PRINT('Hour: ', hour);
PRINT('Minute: ', minute);
PRINT('Second: ', second);
