Reading asset management data
The asset management record has the index 0xF880 and is read with standard PROFINET
mechanisms by the user of the records, for example a tool or program for evaluating these
data.
A user program in the S7-1500 IO controller, for example, can read out the AMR of an
IO device with the RDREC instruction (Index 0xF880).
It is not possible to write to this data record.
Further information
Whether and to which extent a PROFINET device supports asset management data, meaning
whether it makes an AMR available, is specified in the documentation of the respective
device.
