这里PLC地址是83,对应的程序16进制读取地址是53
实际上由于PLC地址从1开始所以这里实际地址应该是52因为计算机从0开始 使用网络调试助手生成报文 使用Python中的内置函数int()。以下是将人员卡号’b’3b44’转换为十进制的示例代码
card_number 3b44
decimal_number int(card_number, 16)
print(decimal_number)使用response[-4:]获取了响应数据的后4个字节作为value96。然后通过struct.unpack(‘f’, value96)[0]将4字节的二进制字符串解包为单精度浮点数并将其打印出来。
#实时电量
