要在C#中实现ModbusRTU的地址映射,首先需要引入一个Modbus库,例如NModbus。接着按照以下步骤实现地址映射:
IModbusMaster master = ModbusSerialMaster.CreateRtu(serialPort);
ushort startAddress = 1;
ushort numRegisters = 10;
ModbusDataStore dataStore = DataStoreFactory.CreateDefaultDataStore();
dataStore.HoldingRegisters.WriteRange(startAddress, new ushort[numRegisters]);
master.DataStore = dataStore;
ushort[] registers = master.ReadHoldingRegisters(startAddress, numRegisters);
master.WriteSingleRegister(startAddress, 123);
通过以上步骤,就可以在C#中实现ModbusRTU的地址映射。需要根据具体的需求来定义映射表和操作方式。
