V
address assignment (Default: 0) is performed using the
BPS Configuration Tool
chapter 8.5.3 "Communication").
Bits
S2, S1, S0
:
If all bits are set to 0, the position data are output.
The position data request cycle must be greater than 10 ms. If no position
data request occurs within 10 s, the laser is deactivated. A response tele-
gram is sent to a repeat position data request after approx. 30 ms.
If only the
S0
bit is set to 1, the marker data are output.
If only the
S1
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 only the
S2
bit is set to 1, position data are output once (laser on –
measurement – laser off).
The response telegram to the single measurement request is sent after
around 40 ms. The single measurement request cycle must be greater
than 40 ms.
Only ever one of the
S2, S1, S0
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:
Diagnostic data request
• Priority 2:
Marker data request
• Priority 3:
Request for one-time transmission of position data
• Priority 4:
Position data request
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").
