The following ASDU leads to the termination of the ClientConnection:
CS104 SLAVE CONNECTION 348: Handle received ASDU
CS104 SLAVE CONNECTION 348: RCVD: 68-24-0C-00-00-00-87-01-14-00-FC-19-0D-94-01-0D-14-FE-FC-19-02-83-DE-C0-04-01-01-09-00-00-5C-44-03-8D-63-08-16-FF
CS104 SLAVE CONNECTION 348: Received I frame: N(S) = 6 N(R) = 0
CS104 SLAVE CONNECTION 348: Enqueue received I-message for processing
CS104 SLAVE CONNECTION 348: Failed to parse ASDU --> close connection
CS104 SLAVE CONNECTION 348: CLOSE CONNECTION!
CS104 SLAVE CONNECTION 348: CONNECTION CLOSED!
This ASDU (TypeID = 135) is not supported by your stack.
Is there a possibility to maintain the connection in case of an unknown ASDU and to handle the ASDU manually or is this behaviour desired and if yes, with which reasoning?
In theory, one would need a RawASDUHandler to decide how to handle these ASDUs to prevent the connection from being terminated.
Hello,
I catch this exception all the time, when server has connection or no connection to client.
it is from the line of listeningSocket.Shutdown(SocketShutdown.Both);
the server is turned off but exception is still happen at this line.
Please support to check and update.
Thank you.
`System.Net.Sockets.SocketException
HResult=0x80004005
Message=A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.
Source=System.Net.Sockets
StackTrace:
at System.Net.Sockets.Socket.UpdateStatusAfterSocketErrorAndThrowException(SocketError error, String callerName)
at System.Net.Sockets.Socket.Shutdown(SocketShutdown how)
at lib60870.CS104.Server.Stop() in D:\work\C#\iec104\lib60870.NET\lib60870\CS104\Server.cs:line 943
This exception was originally thrown at this call stack:
[External Code]
lib60870.CS104.Server.Stop() in Server.cs`
I was wondering why I was getting nonsensical SocketException error messages and I traced it back to his line:
throw new SocketException(87); // wrong argument
The error code is hardcoded even though it is different among OSs.
Error 87 is "Too many users" on Linux and "The parameter is incorrect." on Windows.
I was wondering why I was getting "Too many users" on Linux even though it was my 1st connection attempt.
When a ScaledValue is created with a negative value, it's not encoded correctly to a byte array, so the returned value is invalid. Example code:
// scaledValue.Value is 255 instead of -1
var scaledValue = new ScaledValue(-1);
The problem is located on file ScaledValue.cs, when the Value/ShortValue properties are set.
I want to read
M_ME_TF_1(36) | Short measured value (FLOAT32) with CP56Time2a asdu adress:2063259
from iec60870 server with c# form application but i don't read. Because i don't understand function of lib60870 like a asdureceivedhandler.
Briefly i want to read one variable (m_me_tf_1(36)) and i want this value assign to label1.text. How can i do this?
Thanks for all....
Best regards...

Hi,
I have developed Dotnet Core Web API using this library when I'm giving the request to the API I'm getting the IEC104 parameters data in API response now the issues is when I'm requesting the API again a second time or third time it is not giving the current updated records it is giving me the old records and new records both but I don't want the old records I want only new records.

Can anyone help me with how to clear the ASDUReceivedhandler so that I can get only new records??
Thank you..
Should be
if (!directoryAsdu.AddInformationObject (io)) {
masterConnection.SendASDU(directoryAsdu);
directoryAsdu = new ASDU(masterConnection.GetApplicationLayerParameters(), cot, false, false, 0, currentCa, true);
directoryAsdu.AddInformationObject(io);

Hi, I need a help in order to send command via IEC 104.
I tried to use the standard function SendControlCommand but it turns out that it can not accept the type of command? I am at the beginning od IEC 104 so please if someone could provide me some example with working send command function?
Regards.
How can we send invalid quality message for all information objects from same ASDU to master device?
QualityDescriptor qualityDescriptor = new QualityDescriptor();
qualityDescriptor.Invalid = true;
I can send information object with invalid quality description but I want to send invalid message to without change any value of information objects. Is it possible?
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:

Maybe I'm wrong
Hi.
When I call Connection.Close(); method for IEC104 Client, the system runs into hang. in the server side shows that client disconnected. but my form freezes in client side. I have Traced the Close() method and freezing occurs after execute line workerThread.Join();.
How can I solve the problem.
Thanks.
I've noticed that the Activated method in Server.cs file line 628 , deactivate all previous client connections when a new connection is OPENED.
This detail prevents asdu sending to all previous client connections , even if ServerMode is CONNECTION_IS_REDUNDANCY_GROUP.
I'm not sure if it is a bug or a specific related to the protocol, when the server is a multi client tcp server.
Thanks.
internal void Activated(ClientConnection activeConnection)
{
...
// deactivate all other connections
foreach (ClientConnection connection in allOpenConnections) {
if (connection != activeConnection) {
...
connection.IsActive = false;
...when Connection is trigger the ConnectionEvent.CLOSED Event the Connection.IsRunning is true
do have document for this libraries thanks.
Hello,
As you know for command there is two type. First is direct and second is SBO (select then execute)
In the examples :
con.SendControlCommand (CauseOfTransmission.ACTIVATION, 1, new DoubleCommand (5001, DoubleCommand.ON, false, 0));
The bool select state is set to "false".
Do you have additional example if the bool select is set to "true"?
If I just set to True, it doesnt work. It will need confirmation first before execute command.
Regards,
Hello,,
I have problem to read several data on C#. In example i want to read "single point information", "measured scale" then show the result on "Label or textboxt" simultanously and continuesly. Is it possible?
I tried to copy paste the code from lib60870.NET/examples/cs104-client1/ then change the code from "console.writeln" to "Label.text or textboxt.text" but it doesn't work. =)
I am new comer on C# programming, so please feel free to explain.

Hi!
I am trying to integrate your libray in my code. I am queuing more than 1000 asdu and I noticed that this method is blocking.
I have commented this "for loop" and the communication is faster and the enqueuing procedure is not blocking anymore.
Am I missing something (I am new to this library)?
Best regards.
Hi,
first, thank you for sharing the library, it is a great work.
But I can not find any public method or property to check status of IEC 104 server in
namespace lib60870.CS104
public class Server : Slave
So there is no way to check it.
Can you update this source in new version?
Thank you
// send information objects
var signalAsdu = new ASDU(parameters, cot, isTest, isNegative, oa, ca, isSequence);
foreach (var rtuSignal in rtuSignals)
{
signalAsdu.AddInformationObject(new MeasuredValueNormalized(rtuSignal.IOA, scaleValue(rtuSignal), new QualityDescriptor()));
}
return signalAsdu;
Please see above code. We have created an ASDU unit and trying to add information objects to the unit. We have around 45 Signals to be embedded into the unit object. But the AddInformationObject will not go over 40 because there is no space left due to max length of IEC60870_5_104_MAX_ASDU_LENGTH =249. Is there anyway to go over this limit or we have to send with 2 ASDU unit?
Thanks a lot in advance.
As the title says; I'm just wondering if there is some sort of default stub for this that handles timeout etc., or if this is something that needs to be created from scratch.
I'm using the C# lib. If anyone has some examples of how to do this, that would be helpful too!
I previously posted this here; mz-automation/libiec61850#278, but realized I had the wrong repo!
I am trying to write a client which will read data from 100s of IEC 104 servers (devices in the field).
I create multiple connections and interrogate periodically (1 minute or so).
I observe that data from only some devices is received while data from other devices does not show up on the log.
Do you have any example of how to interrogate multiple devices?
Hi,
I have used example cs104-client3 in the console it is printing the data but I want to take this data into another function how can I call ASDUReceivedHandler explicitly and read data from it??
Thankyou.
