Messaging Namespace PC_SDK

Hello,

I was wondering when the eventhandlers for the Messaging Namespace for PC_SDK are released. 

Best regards,

Hi,

I wonder what information you are referring to? As far as I know, there has been no intention to add any events to the Messaging namespace. Are you already using IPC messaging?

Hi,

In the controller TASK it is possible to connect a trap routine when a message is received in RMQ. But when you sent messages the other direction. That is from Controller to windows Application. I didn't found a solution with current namespace to handle when a message is received in Queue. 

That's where I was referring to. The Eventhandlers when a message is received in Queue. 

The .Net system.messaging has eventhandlers when messages is completely received? I can't use these, because then there is a mismatch between ABB.Robotics.controllers.messaging and system.messaging.

Is it possible to create a handler when a new messages from controller is received in Queue?

 

Best regards,

Hola,

IPC messaging was released in 5.10.

There isn't an event handler to be notified whenever a message is in the queue. Eventhough, you can create a class which fires an event whenever a message is received: just create a thread which is constantly trying to receive a message:

private static void ServerStart()<?:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

{

    IpcMessage message;

    IpcReturnType ret;

  

    try

    {

       // Assume that _ipcSender is created before

        while (_ipcSender != null)

        {

             message = new IpcMessage(Ipc.MaxMessageSize);

           // Try to get a messsage, times out after 50mm

             ret = _ipcSender.Receive(50, message);

 

             if (ret == IpcReturnType.OK)

            {

                 // Process the message        

            }

        }

    }

    catch (Exception e)

    {

        MessageBox.Show(e.ToString());

    }

}
