Reading I&M data records with data record 255 (distributed via PROFIBUS DP)
The modules support standardized access to identification data using DR 255 (index 65000 to
65003). For additional information on the DR 255 data structure, refer to the specifications of
the Profile Guideline - Order No. 3.502.
