Status

The status has to be interpreted bit by bit:

0x0001 general optical fiber error (Lightbus no longer runs)
0x0002 too many errors during address check
0x0010 setting of the transmission power for the IIO boxes to 100% failed
0x0020 resetting of the box addresses failed
0x0030   break location detected
0x0040 setting of box addresses failed
0x0050 testing of box addresses failed
0x0060 testing of box addresses failed
0x0070 testing of box addresses failed

Warnings from the LowIntensityTest (80% transmission power) for information
0x0100 setting of transmission power for the IIO boxes to 80% failed, e.g. during reset
0x0110 box test with extreme test telegrams failed
0x0120 box test with extreme test telegrams failed
0x0130 box test with extreme test telegrams failed

Err Handler

If an error occurs after FA00:06 to FA00:09, an internal error handling routine is started.
This counter indicates how often this routine was started and should be <= the sum of :06 to :09.

Index FA01

Each Lightbus box has a byte counter, which counts the CRC/parity errors. In the EL6720 these local counters can be shown in the respective subindices for 0xFA01.
