FatekProgramOverTcpReadAsync 方法 (String, UInt16)

批量读取PLC的字节数据，以字为单位，支持读取X,Y,M,S,D,T,C,R,RT,RC具体的地址范围需要根据PLC型号来确认，地址可以携带站号信息，例如 s=2;D100
Read PLC byte data in batches, in word units. Supports reading X, Y, M, S, D, T, C, R, RT, RC. The specific address range needs to be confirmed according to the PLC model, The address can carry station number information, such as s=2;D100
