ModbusInfoBuildReadModbusCommand 方法 (String, Int32, Byte, Boolean, Byte) |
构建Modbus读取数据的核心报文,需要指定地址,长度,站号,是否起始地址0,默认的功能码应该根据bool或是字来区分
To construct the core message of Modbus reading data, you need to specify the address, length, station number,
whether the starting address is 0, and the default function code should be distinguished according to bool or word
