Sending cyclic message using CANoe - IL DLL

I have a configuration setup with two CAN nodes and an attached database. I have added a CANOEILNLVECTOR.dll to both the nodes. By adding this Dll file all my messages are sent cyclic as I see in trace window. Now I set some value for a signal in a message, For Eg:

variables
{
  message Battery_Traction Batt_msg;
}

on start
{
  Batt_msg.Isolation_Signal = 0x02; //0x02:On
  output(Batt_msg);
}

What I see on trace is: The message is cyclic but only for the first instance the value set by me above appears in trace. For all of the rest times the signal value in the message in set to default.

As seen in the image value 0x02 is sent only once.

Trace.asc

I am not sure what could be the problem, as seen in image attached value set by me is only sent once.

Solution

  • When using output you are putting the message directly onto the CAN bus, but you are not changing the value inside of your (simulated) node, so the interaction layer is still sending the old value.

    You can change the signal value in the interaction layer by just putting a $ in front of the signal name and set the value.

    In your case most likely $Isolation_Signal = 0x02

    Outputting the message on the CAN bus at the right time, with the right cycle time and so on will be handled by the interaction layer.
