Identification and maintenance data

12.8.1 Reading out and entering I&M data
I&M data
Identification and maintenance data (I&M data) is information saved on the module. The data
is:
• Read-only (I data) or
• Read/write (M data)
Identification data (I&M0): Manufacturer information about the module that can only be
read. Some identification data is also printed on the housing of the module, for example
article number and serial number.
Maintenance data (I&M1, 2, 3): Plant-specific information, for example installation location.
Maintenance data for S7-1500R/H is created during configuration and downloaded to the
redundant system.
S7-1500R/H supports identification data I&M0 to I&M3. Exception: The synchronization
modules for S7-1500H only support identification data I&M0.
The I&M identification data supports you in the following activities:
• Checking the plant configuration
• Locating hardware changes in a plant
• Correcting errors in a plant
Modules can be clearly identified online using the I&M identification data.
Options for reading out I&M data
• Over the user program
• From the display of the CPUs
• Via STEP 7 or HMI devices
