Additional information
Reading I&M data records with data record 255 (distributed via PROFIBUS DP)
The modules support standardized access to identification data via DS 255 (index 65000 to
65003). You will find more information on the data structure of DS 255 in the specifications of
Profile Guidelines Part 1: Identification & Maintenance Functions - Order No. 3.502, version
1.2 from October 2009.
