功能說明

簡化 Modbus 相關設備資料讀取及寫入作業

主要功能

1. 支援 Scan 方式掃描可用的 slave id
2. 支援讀取功能
   • ReadCoils (0x01)
   • ReadDiscreteInputs(0x02)
   • ReadRegisters(0x03)
   • ReadInputRegisters (0x04)
3. 支援寫入功能
   • WriteCoil(0x05)
   • WriteRegister(0x06)
   • WriteCoils(0x15)
   • WriteRegisters(0x16)

安裝方式

• 使用 Nuget 方式進行安裝 https://www.nuget.org/packages/hanson.modbus.slave.service/

使用範例

• RTU & ASCII 使用範例

// 使用 SimpleFactory 建立 RTU 實體 (依實際需求指定不同實體產生的函式)
string comport = "COM1";
byte slaveId = 1;
ushort address = 0;
ushort dataReadLength = 16;
SerialPort serial = new SerialPort(comport);

using (var client = SimpleFactory.CreateModbusRtuClient(serial))
{
	client.Open();

	//讀取方式 
	var readBytes = client.ReadRegisters(slaveId,address,dataReadLength);

	// 寫入方式
	ushort[] values = new ushort[]{0,1,2,3,4,5,6,7};
	var writeBytes = client.WriteRegisters(slaveId,address,values);
    
}

• TCP & RTU over TCP & ASCII over TCP 使用範例

string ip = "127.0.0.1";
int port = 502;
byte slaveId = 1;
ushort address = 0;
ushort dataReadLength = 16;

using (var client = SmipleFactory.CreateModbusRtuOverTcpClient(ip, port))
{
	client.Open();
    
    //讀取方式 
    var readBytes = client.ReadRegisters(slaveId, address, dataReadLength);

    // 寫入方式
	ushort[] values = new ushort[]{0,1,2,3,4,5,6,7};
	var writeBytes = client.WriteRegisters(slaveId,address,values);
                    
}
