Leuze electronic BPS 8 Original Operating Instructions page 101

A0 and A1 are the address bits. If several BPS 8 operate in an RS 485 network, an address
configuration is required. Every BPS 8 is supplied with the Standard address 0. The
address assignment (Default: 0) is performed using the BPS Configuration Tool (see
chapter 8.5.3 "Communication").
NOTE
RS485 network!
An MA 8-01/MA 8-02 connection unit is mandatory for the operation of the BPS 8 in an
RS485 network (see chapter 4.2 "MA 8-01 / MA 8-02 connection unit").
Bit F0:
Bit F2:
Only ever one of the F2 and F0 bits should be set in the request byte, because the BPS can
only respond to one request. If several bits are set, the function with the highest priority is
executed.
Priority of the bits in the request byte:
• Priority 1:
• Priority 2:
• Priority 3:

If this bit is set to 0, the position data is output.
The request cycle must be greater than 10 ms. If no position data request
occurs within 10 s, the laser is deactivated. A response telegram is sent
to a repeat position data request after approx. 30 ms.
If this bit is set to 1, the diagnostic data are sent in response. An indicated
error is reset once all diagnostic data has been polled. This is indicated
by the status LED changing from red to green.
If this bit is set to 1, the Standby mode is activated.
The polygon wheel motor and the laser are switched off in Standby. Diag-
nosis of the read system cannot be performed. When the device is reac-
tivated (bit F2 = 0), the system start-up time is approx. 5 s.
