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 more 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.
The specifications are available, for example, on the PROFIBUS & PROFINET International (PI)
website on the Internet (https://www.profibus.com/).
