The Run method only activates the message transfer. After termination of the Run method it is never assured that the data have already been transferred. The Run method only causes that the PmaCommMsg object is "placed" in the queue of messages that have to be just transferred.
The PmaCommMsg object waits in the queue until its turn (this functionality is the internal PROMOTIC property and the designer doesn't need to care about it). Then he starts to transmit its data and waits for the requested received data, reads the data and the whole process is finished by triggering of the onEndOfTransfer event. The Run method doesn't wait for these actions any more.
The PmaCommMsg object can find itself in two states - the state when the transfer doesn't proceed and the state when the transfer proceeds (i.e. state between calling the Run method and the onEndOfTransfer event). The Run method can be called only over the object in the state when the transfer in this object doesn't proceed. This state can be found out by the GetReady method.
var oCommMsg = pMe.Pm("/Comm/mr");
if (oCommMsg.GetReady())
oCommMsg.Run();
