Data record structure for I&M data
Reading I&M data records (distributed via PROFINET IO)
You can directly access specific identification data by selecting
Read data record
(RDREC
instruction). You obtain the corresponding part of the identification data under the relevant
data record index.
The data records are structured as follows:
