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.
