一个字=16个位，对应1 2 4 8 16 32 64 128等，那么-1 -2 -4 -8这些对应的什么呢 ，是什么意思？
答：不可按“对应1 2 4 8 16 32 64 128等”一概而论，楼主所言的只是对不带符号的WORD数据类型。至于负数更不能套用了。
1、一个字为16个位，但一个字可以表示不同的数据类型。
WORD数据类型（不带符号，0~65535）与INT数据类型（带符号，-32767~32768）：
通常情况下WORD用于逻辑运算，INT用于数学运算；
在使用梯形图或SCL等语言编程时区分较严格。
在使用语句表编程时系统不检测数据类型是否匹配，即WORD与INT在用法上没有什么区别（WORD可做数学运算，INT也可作逻辑运算）。
2、有关负数：
负数转换为二进制，就是将其相反数（正数）的补码的每一位变反（1变0，0变1）最后将变完了的数值加1，就完成了负数的补码运算。这样就变成了二进制。
举个例子：
将-1变成二进制。
①首先确定二进制的位数，假定为16位，即可以表示-32768到32767的所有十进制整数。
②将-1的相反数，也就是1表示为二进制0000 0000 0000 0001（十六进制表示为0x0001）
（由于四位二进制可以表示为一位十六进制，故一般将二进制按四位进行分段表示）
③将这个二进制变反，可以得到1111 1111 1111 1110（十六进制HEX表示为0xFFFE）
④将变反后的数值加上1，得到-1的二进制表示1111 1111 1111 1111（十六进制表示0xFFFF）
