Device boot-up is so fast that no other nodes on the bus have yet
been detected when the boot-up message is sent.
Measure
Check cabling: cable specification adhered to, broken cable,
maximum cable length exceeded, correct terminating resistors,
cable screening earthed, all signals terminated?
If necessary, replace device as a test. If a different device works
without errors with the same cabling, send the device to the
manufacturer for inspection.
