Bus load
51.2%
Bits used per second
2,56,000 bps
Baud rate
5,00,000 bps
Frames per second
2,000
Bits per frame
128 bits
Bus load is within a generally safe operating range (typically kept under 70%).
Formula and working
Bus load % = (frames/sec × bits/frame ÷ baud rate) × 100
- 1
Collect the inputs
CAN bus baud rate = 500,000; Average bits per frame (incl. stuffing/overhead) = 128 bits; Frames transmitted per second = 2,000 fps
- 2
Apply the formula
Bus load % = (frames/sec × bits/frame ÷ baud rate) × 100
- 3
Result
Bus load = 51.2
