How I can set direction as only Tx message should be there and filter out TxRq

Question

I am writing a CAPL script to mimic a CAN message on network. While I am getting intended message, direction is both Tx & TxRq. How I can filter out and send only Tx message.

I tried CANID.dir=1 (tx) however not getting intended result.

Message details

I tried, setting direction as CANID.dir=1 (tx).

Answer 1

According to your screenshot, I assume took from the Trace window, you are looking at duplicate entries that spark confusion.

The entries marked as Tx are telling you that there is, indeed, a CAN frame with direction "outgoing" from your measurement system (your Vector Node).

The entries marked as TxRq are send requests. You may change settings for send requests in the Vector Hardware Configuration tool (ref).

TxRq is not a "direction" per se, just a way to indicate a different type of log in the Trace window. Remember that the only directions available are Tx and Rx (all frames either go out of your node or come into your node).

More about send requests. The following is an extract, I don't remember from which Vector knowledge base entry

By default, this box [the one in the Vector Hardware Configuration] is unchecked because most users do not require this feature. This feature displays the TxRq messages with a time stamp in the Trace window of CANoe. These are requests to send messages by CANoe that have not yet been transmitted onto the CAN bus. If they have been transmitted on the CAN bus, they would be Tx messages.

Vector Network Hardware Configuration

If you get similar issue, pls go to simulation setup, channel on which you have simulated node, go to Network hardware & untick Activate TxRq
