11.3 使用示例

开机运行示例

while (true) { 
    var status;
    status = ReadStatus('system.TIME_SECOND');  //ReadStatus：读取数据点质量戳
    console.log('system.TIME_SECOND status is ', status);
    if(status){ // 如果该点存在并且质量戳为Good
        var curVal;
        curVal = ReadInt('system.TIME_SECOND'); //ReadInt：从指定数据点读取整数 
        console.log('system.TIME_SECOND value is ', status);
        WriteInt('user.test',curVal); //WriteInt：向指定数据点写入整数 
    }
    Sleep(1000); //休眠1秒钟
}

定时示例

var status;
status = ReadStatus('system.TIME_SECOND'); //ReadStatus：读取数据点质量戳
console.log('system.TIME_SECOND status is ', status);
if(status){
    var curVal;
    curVal = ReadInt('system.TIME_SECOND'); //ReadInt：从指定数据点读取整数 
    console.log('system.TIME_SECOND value is ', status);
    WriteInt('user.test',curVal); //WriteInt：向指定数据点写入整数 
}
