WARNING
5.3.3 IO message in case of an error
If, in case of a serious error, a correct position calculation cannot be ensured, the output of
the position within the process data is blocked and instead an error code output. These
manufacturer-specific error codes are outside the valid value range and permit a detailed
error analysis.

Evaluate bit 31 of the input data using your control system to detect serious errors!
If, in the case of serious error, it cannot be ensured the position output is correct, this
situation is indicated by setting the most significant bit 31. The position value is then
outside the valid range and can be identified as clearly erroneous (see section 5.3.2
“ Diagnostics message ” on page 22).
