答复：? 字节计数是从2到250（含）的二进制数。它是正常响应中字节计数之后和错误检查之前的字节数。注意，字节计数等于响应中返回的寄存器数的两倍。设置了***多250字节（125）的寄存器，以便整个响应可

以容纳一个256字节的数据块。? 寄存器在数据字段中按数字顺序返回，在数据字段的前两个字节中有***数量的寄存器，在***两个字节内有数量的寄存器。数据字段中***个寄存器的编号等于起始寄存器编号加1。在每个寄存器的低位字节之前发送高位字节。查询：? 不允许地址为0，因为此请求不能是广播请求。? 功能代码等于4。? 起始模拟输入号的长度为两个字节。起始模拟输入数可以是小于所连接CPU中可用的模拟输入数的任何值。它等于该请求的正常响应中返回的***个模拟输入的数量的1。

Response: ? The byte count is a binary number from 2 to 250 inclusive. It is the number of bytes in the normal response following the byte count and preceding the error check. Note that the byte count is equal to two times the number of registers returned in the response. A maximum of 250 bytes (125) registers is set so that the entire response can fit into one 256-byte data block. ? The registers are returned in the Data field in order of number with the lowest number register in the first two bytes and the highest number register in the last two bytes of the Data field. The number of the first register in the Data field is equal to the Starting Register Number plus one. The high order byte is sent before the low order byte of each register.Query: ? An Address of 0 is not allowed as this request cannot be a broadcast request. ? The function code is equal to 4. ? The Starting Analog Input Number is two bytes in length. The Starting Analog Input Number may be any value less than the highest analog input number available in the attached CPU. It is equal to one less than the number of the first analog input returned in the normal response to this request.
