CAN Bus Utilization¶
CTR Electronics goes through great efforts to make our products efficient on CAN bus bandwidth. This article highlights the average default bus utilization of supported Phoenix 6 devices. Users should keep total CAN bus utilization below 90% to prevent any unexpected behavior. Information on changing the default CAN update frequency is available in the status signal and control request documentation.
Note
Using Phoenix API will automatically start up a diagnostic server which adds a constant 0-5% total CAN bus utilization.
