If a CAN device must read an output message, the CAN device must

Important:
Do not define any data fields for RTR Frame messages.
The Message ID setting set in the RTR Frame output message

the RTR Frame message, the CAN device requires an input message
with the same message ID as the RTR Frame message.

from a CAN device. When an RTR Frame message with the same
message ID is received, the RTR Data message is sent. RTR Data
Note:
Typically, a message marked as RTR Data should have a rate of
0 Hz because it is not sent periodically.
