要在C#中實(shí)現(xiàn)ModbusRTU的地址映射,首先需要引入一個(gè)Modbus庫,例如NModbus。接著按照以下步驟實(shí)現(xiàn)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);
通過以上步驟,就可以在C#中實(shí)現(xiàn)ModbusRTU的地址映射。需要根據(jù)具體的需求來定義映射表和操作方式。
