    Hello!

    I am working on a PiXtend V2-L which is connected via CAN bus to a VESC 6+ motorcontroller.
    I sent the message:
    cansend can0 0000033D#3E800000
    And my motor started spinning at 1000RPM

    How the message works:
    00000 - command ID (RPM - 3) - Adress (61 - 3D) # - RPM ( 1000 - 3E8) - 00000

    The candump looks like this:

    The struggle now is to send and read these messages in CODESYS

    Tried to make it work with CANopen, but my motorcontroller is not compatible

    Is there any kind of way to read and write raw messages in codesys???

    Any kind of help that puts me in the right direction would be of huge help
