WebE.g. With 48MHz CAN clock frequency, 125K bit rate can be achieved with NBT = 8, 12, 16 and 24 Tq, with 0% deviation in the bit rate. From these four choices an appropriate value of NBT needs to be determined along with the bit time segments and the RJW value. While determining these values, the following characteristics have to CAN data transmission uses a lossless bitwise arbitration method of contention resolution. This arbitration method requires all nodes on the CAN network to be synchronized to sample every bit on the CAN network at the same time. This is why some call CAN synchronous. Unfortunately the term synchronous is imprecise since the data is transmitted in an asynchronous format, namely without a clock signal. WebSample Rate - The legislated signals have a slower update rate than normal CAN bus channels. Active vs Passive - These signals are not broadcast by default, and need to be requested by the measurement device. This requires setting the ‘CAN Acknowledge’ mode to ‘Active’ rather than ‘Passive’ in Simcenter Testlab CAN settings. how math builds intuition
