Hi everybody,

I am using the Motor Control Toolbox for the mpc5643L. In my CAN Network are 2 TRK-USB-MPC5643L and the PCAN-USB Interface. Sending my message with the ID 001h works perfectly fine.

In the Background the RTR-Frame with the ID 1FFFFFFFh is running cyclical with 0.7. The cyclical appearence of this RTR-Frame appears only when I use more than one TRK-USB-MPC5643L in my CAN-Network.


How can I suppress the sending of this frame?

What is the usage of this Frame?


Thank you very much for any advise or Help
