What are I&M data?
For PROFINET and PROFIBUS, I&M stands for "Identification and Maintenance". The I&M data contain information about the PROFINET participants. These are in some cases from the manufacturer (order number, serial number, etc.), but can also be described by the user (location, service contact, etc.).
The I&M data of all PROFINET participants can be read out and evaluated in the automation network with standard functions.
The PROFINET switch has appropriate I&M data records.
