¥¥¥CAN总线模块 CM202 ¥¥¥
在程序初始化时将VW0清零(如果是不需要记忆的变量,直接将dVarName清零也可)或者在数据块中将VW0设置为零。
则以后需要以字类型访问变量时就用wVarName,需要以双字类型访问变量时就用dVarName。完全不需要类型转换。
本方法可以极大的减少程序语句数,使程序更简洁、可读性更好,由于不需要做耗时的类型转换,程序运行效率也得到提高。且数学运算量越大,效率提高越明显。
缺点是要多占用两字节的内存,以后程序中不能使用VW0。但S7-200的RAM空间很大,一般是用不完的,以226为例,有多达10K的RAM,偶从来没有超过1K。这些RAM都是花钱买来的,不用白不用,不用也是浪费了。
同理,如果有字节型变量经常需要与字类型变量相互转换,让字节变量占用一个字的内存宽度浪费一个字节,避免类型转换。
