9.3.2.1 Query to the BPS 8 (control byte)
Notice!
A0 and A1 are the address bits. If several BPS 8's operate in one network, an address con-
figuration is required.
Notice!
If the F0 bit is set to 1, the diagnostic data are sent in response. Any error indicated is reset.
This may be recognised by the status LED changing from red to green.

).
1) In order to extend the service life of the device, it can be switched to SLEEP mode. In
SLEEP mode, the motor and laser are switched off. Diagnosis of the read system cannot
be performed.
When reactivating the device, the system takes approx. 5s to boot. It reports after this time
with a message "System ready".
