104server Received sequence number out of range
When i start 104server and client connect, it's running normal. But when S num about 8500, some error occured this is the debug log: `CS104 SLAVE CONNECTION 1: SEND I (size = 18) : 68-10-AC-42-3A-00-0B-01-01-00-01-00-6E-00-00-DF-00-00

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); }`
What are you using as client. It seems the client is sending out of sync sequence numbers.
Hi, Thanks for replay. When the error occurred, every time , the seqNo is less than 1000,and sentASDUs[newestSentASDU].seqNo is equal ( seqNo + 8000) Like, seqNo=331 and sentASDUs[newestSentASDU].seqNo=8331
This is the code before error occured @.***
