Module ID: 1020 or submodule ID: 1
The module is used to implement two parameters that facilitate free scaling of the output values
for position value and velocity value.
The free resolution is used if the adjustable resolutions that can be set in module 1 or module 10
are not suitable for the application. In modules 1 and 10, the
Resolution
parameter is set to value
Free resolution
. The measurement values are then converted for output with (multiplied by) the
parameter values stored in this module and output.
The module contains parameters (with parameter data length of 4 bytes), but no input data and
no output data.

The module enables the transmission of the current distance between the BCB and read head
(in mm) to the PROFINET master.
This can be used to check the correct reading distance in the entire system.
Example: A fault in the position value determination is caused by an impermissible reading dis

If value

If value

is transmitted, a valid distance could not be calculated.
