Signal Delay
The signal delay at forwarding of a CAN message consists of a fixed
processing time of the microcontroller of about 30
μ
s and a variable
delay depending on message length and transfer rate. Thus, the
signal delay of a CAN message with an 11-bit ID and eight data
bytes at 500 kbit/s is about 260
μ
s.
