4.9 Maintenance
4.9.1 I&M data (identification and maintenance)
Definition and properties
Identification and maintenance data (I&M) is information saved to module memory in order
to provide support when:
•
Checking the plant configuration
• Locating hardware changes in a plant
Identification data (I data) is module information (some of which may be printed on the
module housing) such as the order and serial number. I data is read-only vendor-specific
module data.
Maintenance data (M data) is plant-specific information such as the location identifier and
installation date. M data is created during configuration.
The modules can be uniquely identified in online mode by means of the I&M data.
Further information
To find out whether and to what extent a PROFINET device supports I&M data, refer to the
documentation of the relevant device.
4.9.2 Loading I&M data to PROFINET IO devices and your modules
Which I&M data can be loaded to PROFINET IO devices and your modules?
You can load I&M 1 data (plant designation and location identifier) and/or I&M 2 data
(installation date) and/or I&M 3 data (additional information) to the actual hardware.
Requirements
• In the project settings (Options > Settings, Hardware configuration > Compiling and
downloading), the option "Download I&M data" must be enabled.
• There is an online connection to the PROFINET IO devices and the modules to which you
want to load I&M data.
• You have entered the I&M data you want to download in the properties of the respective
PROFINET IO devices and your modules (Inspector window: "Properties" tab > "General"
tab, Settings > Identification & Maintenance).
