The code is examples cs104-server, just modify the send frequency
`while (running && server.IsRunning())

{
Thread.Sleep(100);
newAsdu = new ASDU(server.GetApplicationLayerParameters(), CauseOfTransmission.PERIODIC, false, false, 0, 1, false);
var rnd = new Random().Next(0, 360);
newAsdu.AddInformationObject(new MeasuredValueScaled(110, rnd, new QualityDescriptor()));
server.EnqueueASDU(newAsdu);
}`
