on a664Message

Valid for: CANoe DE • CANoe4SW DE Note
CAPL programs are by default not transparent to bus events. This means that a CAPL node in the evaluation branch of the measurement setup will block the data flow to its right side. You must explicitly code the forwarding of messages in CAPL nodes in the evaluation branch. In order to re-use this code snippet in the Simulation Setup of your CANoe DE product you have to add conditional compilation. Otherwise a recursion will occur. Forward AFDX message event: 
on a664Message * {
  #if MEASUREMENT_SETUP
  output(this);
  #endif
}
Detect real message in CAPL: 
on a664Message * {
  if (this.dir == RX) {
    if (!this.SIMULATED) {
      write("AFDX message received from real system");
    }
    else {
      write("AFDX message received from simulated component");
    }
  }
}
