模拟输入数量值的长度为两个字节。它包含从1到125（含）的值。起始模拟输入值和模拟输入数量值之和小于或等于所连接CPU中可用的模拟输入数量。起始模拟输入数和模拟输入数字段的高位字节作为这些字段中的***个字节发送。低位字节是这些字段中的***个字节。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模拟输入数的两倍。设置250字节（125）的模拟输入，以便整个响应可以适合一个256字节的数据块。? 模拟输入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的模拟输入数量***少，在***两个字节，模拟输入数量***多。数据字段中***个模拟输入的数字等于起始模拟输入数字加1。在每个模拟输入的低位字节之前发送高位字节。

                         产品英文详情料:

The Number Of Analog Inputs value is two bytes in length. It must contain a value from 1 to 125 inclusive. The sum of the Starting Analog Input value and the Number Of Analog Inputs value must be less than or equal to the highest analog input number available in the at-attached CPU. The high order byte of the Starting Analog Input Number and Number of Analog Inputs fields is sent as the first byte in each of these fields. The low order byte is the second byte in each of these fields. 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 analog inputs returned in the response. A maximum of 250 bytes (125) analog inputs is set so that the entire response can fit into one 256-byte data block. ? The analog inputs are returned in the Data field in order of number with the lowest number analog input in the first two bytes and the highest number analog input in the last two bytes of the Data field. The number of the First Analog Input in the Data field is equal to the Starting analog input number plus one. The high order byte is sent before the low order byte of each analog input.
