8.6.3 Module 1 – Position value
Module ID: 1001 or submodule ID: 1
Module for the output of the current position value. The module also includes the most important
parameters for formatting the output value.
The module contains parameters (with parameter data length of 6 bytes) and input data (with
consistent input data length of 4 bytes), but no output data.

Resolution of the position value. Affects only the
PROFINET output. The resolution has no effect on
the set parameter values such as offset or preset:
001 = 1: 0.001
010 = 2: 0.01
011 = 3: 0.1
100 = 4: 1
101 = 5: 10
110 = 6: Free resolution

NOTICE
Convert numerical values when changing the unit of measurement!
If the unit of measurement is changed from metric to inch (or vice versa), previously entered numerical
values (e.g. for offset, preset, limit values etc.) are not automatically converted.
Example: Offset = 10000 mm – after changing from metric to inch: Offset = 10000 inch/100
Manually convert the numerical values when changing the unit of measurement.
