12.4 I&M data
Identification and maintenance data (I&M) are information stored in a module which
supports you in:
ƒ Checking the system configuration
ƒ Locating hardware changes in a system
ƒ Eliminating errors in a system
Identification data (I data)are information on the module, as for instance order number
and serial number, which are partly printed on the module housing. I data is manufacturer
information on the module and can only be read.
Maintenance data (M data)are system−dependent information, as for instance mounting
place and date of installation. M data is created during the project planning phase and
written onto the module.
The I&M data serves to unambiguously identify modules online.
Via "read data record" you can access certain identification data. Here, you address parts
of the identification data via the corresponding index.
The data records have the following structure:
