7.2
Selection of Operating Mode
DT measuring mode is factory-set.
Changes can be implemented in parameter setup mode, using bits 5 ... 7 of parameter setup byte 26.
- 0 = 000 = DF
- 1 = 001 = DT
- 2 = 010 = DW
- 3 = 011 = DX
- 4 = 100 = DM
Where modified data are to be written onto the EEPROM, bit 4 of parameter setup byte 26 must be set to ’1’.
7.3
Configuration Data
For input and output data, the following configurations are available:
Mandatory
class 1
D1 hex
2 words input consistency
class 2
F1 hex
2 words of input data, 2 words of output data for preset value, consistency
Optional
class 1
D0 hex
not implemented in the sensor
class 2
F0 hex
not implemented in the sensor
7.4
Cyclical Data Exchange – Input (Slave -> Master)
The sensor outputs position data which are mathematically signed. The SF (scale factor) parameter can be
used to invert a given mathematical sign. Resolution is also defined via SF.
Octets in a telegram are arranged in a Profibus-compliant manner (big endian), that means, the MSB always
comes first and the LSB is always the last one.
