Reading I&M records with record 255 (distributed configuration via PROFIBUS)
Use Read data record ("RDREC" instruction) to access specific identification data.
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 Guidelines Part 1: Identification & Maintenance Functions - Order no.: 3.502,
Version 1.2, October 2009.
