NOTE
If bit SLEEP (bit 6) in status byte is set to 1, the BPS is in Standby mode. In a diagnostic
response during Standby mode, the bits CALC, DB and SLEEP are set as follows:
• CALC = 0
• DB
= 0
• SLEEP = 1
In Standby mode, the data bits P00 to P20 are always 0.
NOTE
With the BPS Configuration Tool, the user can individually adapt the binary protocols 1 and 6
to the specific requirements of the application. The binary protocols 2, 3 and 4, on the other
hand, have a fixed structure and cannot be modified.
