BeckhoffAdsNetReadAsync 方法

异步读取支持Hsl特性的数据内容，该特性为HslDeviceAddressAttribute，详细参考api文档说明
Asynchronously read the data content of the Hsl attribute. The attribute is HslDeviceAddressAttribute, please refer to the api documentation for details.

读取PLC的数据，地址共有三种格式，一：I,Q,M数据信息，举例M0,M100；二：内存地址，i=100000；三：标签地址，s=A
Read PLC data, there are three formats of address, one: I, Q, M data information, such as M0, M100; two: memory address, i = 100000; three: tag address, s = A

批量读取PLC的数据，需要传入地址数组，以及读取的长度数组信息，长度单位为字节单位，如果是读取bool变量的，则以bool为单位，统一返回一串字节数据信息，需要进行二次解析的操作。
To read PLC data in batches, you need to pass in the address array and the read length array information. The unit of length is in bytes. If you read a bool variable, it will return a string of byte data information in units of bool. , which requires a secondary parsing operation.
