Record Structure For I&M Data - Siemens SIMATIC S7-1500 System Manual

9.6.2 Record structure for I&M data
Reading I&M records (centrally and distributed via PROFINET IO)
To directly access specific identification data for a module, use Read record ("RDREC"
instruction). Under the associated record index you obtain the corresponding part of the
identification data.
The records are structured as follows:
