举例如下：
D36数据为1234H，其ASIC表示为30H、32H、33H、34H；
D36被拆分 1 2 3 4，其二进制对应码如下：
1 2 3 4
0001 0010 0011 0100
表现为：× × × × MY11断、MY10断、MY9通、MY8断；
MY7断、MY6断、MY5通、MY4通、MY3断、MY2通、MY1断、MY0断；
g. D37为SUM校验数据。它是将通讯协议中除00H、05H及D37外其余所有数据加在一起后所得的1个字的低位数据然后拆
分为D37H、D37L（仍然需要转化为ASIC码）。
2．只改变一个开关量的通讯协议：
在很多情况下，可能通过计算机只操作某个开关，这时就可使用以下通讯协议：
[img]200412311011020611.jpg[/img]
a. 00H并非必须的，但可为某些编程时需要添无效数据以构成完整的数据帧。
b. 05H是发送给DDMF1-8DO的起始控制位数据，它是必须的；
c. D35： DDMF1-8DO所在RS－485网络中的地址，我们可以理解为从站地址，D35由D35H、D35L构成，它是从站地址数
据的ASIC码表现形式，例如DDMF1-16DO模块地址为01，则D35＝H3031（ASIC码的16进制表示方法），即D35H＝30H、
D35L＝31H，表示该从站地址是01号； NEW BANNER OPPOSED EMITTER & RECEIVER SM31EL
