+
+The Modbus TCP protocol implementation.
+
+## Example
+
+A simple example which reads the voltage between L1 and N of a Janitza device.
+
+```csharp
+string host = "modbus-device.internal";
+int port = 502;
+
+using var client = new ModbusTcpClient(host, port);
+await client.ConnectAsync(CancellationToken.None);
+
+byte unitId = 5;
+ushort startAddress = 19000;
+ushort count = 2;
+
+var registers = await client.ReadHoldingRegistersAsync(unitId, startAddress, count);
+float voltage = registers.GetSingle();
+
+Console.WriteLine($"The voltage between L1 and N is: {voltage:N2}V");
+```
