MelsecFxLinksOverTcpReadAsync 方法 (String, UInt16)

批量读取PLC的数据，以字为单位，支持读取X,Y,M,S,D,T,C，具体的地址范围需要根据PLC型号来确认，地址支持动态指定站号，例如：s=2;D100
Read PLC data in batches, in units of words, supports reading X, Y, M, S, D, T, C. The specific address range needs to be confirmed according to the PLC model, The address supports dynamically specifying the station number, for example: s=2;D100
