 　     以S7-200为例，它的内存格式与我们常用的PC机正好相反，它是高字在前，低字在后的。所以我们可以将字变量放在后两个字节，在程序初始化时将前两个字节清零(程序的其它地方不得使用这两个字节)。
    如我们定义符号时将字变量定义在VW2，同时保持VW0的值为零。则程序中可以用VW2以字型访问该变量，同时也可以VD0以双字型访问，避免了类型转换。
    为了避免使用时混淆，最好以明确的符号定义来区分字类型和双字类型。在此强烈推荐类匈牙利命名法：以前缀指示变量类型，用首字母大写的有意义的英文单词的组合作变量名。本人习惯用以下缀：b----字节型变量(byte)
    w----字型变量(word)
    d----双字变量(double)
    r----实型变量(real)
    f----位变量(flag)
    btn---自复位按钮式输入(button)
