1、串口调试工具发送FINS，读取CP1HD区的数据读取DM00001个通道的值发送：@00FA00000000001018200000000017C*CR其中0101是命令码82是DM区0000表示通道号00表示通道中的位0001表示读取一个通道值接收：@00FA004000000001010000010042*CRDM0000=0100其中0101是命令码0000是响应码0100是读取到的值

2、读取D10000开始连续10个通道的值发送：@00FA000000000010182271000000A08*CR2710Hex＝10000000AHex=00

3、10个通道接收：@00FA004000000001010000000100000000000000000000000000000000000042*CRD10000=0001D10001～D100009=0000因为FINS发送命令，一帧命令最大读取的是540个字节，即270个通道。所以要读取270个通道以上的数据，需要分几侦命令来发送。读取D10000开始连续270个通道的值发送：@00FA000000000010182271000010E0D*CR2710Hex＝10000010EHex＝270个通道接收：@00FA0040000000010111

8、续270个通道的值发送：@00FA000000000010182281E00010E77*CR281EHex＝10270010EHex＝270个通道接收：@00FA00400000000101110B027000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
