Protocols for position value output
Leuze electronic BPS 8 106
TNT 35/7-24V
Position data
The position data are output in two's complement as a 32-bit signed integer value by
default in millimeters with a resolution of 1 mm (see chapter 8.5.2 "Position detection")
The P00 data bit corresponds to the LSB, the P31 data bit corresponds to the MSB.
Function identifier
See request telegram, See "Function identifier" on page 104.
Diagnostic data
The 4 bits DIA0 to DIA3 contain coded diagnostic data:
0000 (0
d
) = No diagnostic data exist
0001 (1
d
) = Interface error
0010 (2
d
) = Motor error
0011 (3
d
) = Laser error
0100 (4
d
) = Internal error
0101 (5
d
) = Request contains invalid data
0110 (6
d
) … 1110 (14
d
) = Not currently used
1111 (15
d
) = Activation of positioning mode running (BUSY)
