Modbus Protocol for .NET | TCP
The Modbus TCP protocol implementation.
Example
A simple example which reads the voltage between L1 and N of a Janitza device.
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 of device #{unitId} between L1 and N is: {voltage:N2}V");
