5.2 Commissioning mode
Commissioning mode is a unique feature of normal operation in device classes HUEBNER 2.1
and 2.2. In addition to the preset value and counting direction, both of which can also be changed
in normal operation, scaling is also possible via teach in process in online mode. To do so, only
bit manipulation in the status of the DDLM_DATA_EXCHANGE mode is required. The data is
transmitted as follows as a 4 eight bit wide word in each cycle:

Transmission of data within a DDLM_DATA_EXCHANGE cycle
The status bits have the following meaning:
Bit 25
0 = angular encoder not ready for oper-
ation
1 = angular encoder ready for operation
Bit 26
0 = commissioning mode
1 = normal mode
Bit 27
0 = software limit switch
min < actual process value < max.
1 = software limit switch
min > actual process value > max.
Bit 28
0 = counting direction clockwise
(Looking towards end of shaft)
1 = counting direction anti-clockwise
(Looking towards end of shaft)
Bit 31
0 = normal operation
1 = set preset value
5.2.1 Adopt preset value
the preset value can be adopted from the basic device settings both in normal mode and in com-
missioning mode. It is adopted regardless of whether bit 26 is set.
