8.7 Identification and maintenance data
8.7.1 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
● Readable/writable (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 is created during configuration and loaded to the module.
Note
The CPU supports identification data (I&M0) only for the High Feature (HF) electronic
modules.
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
● Via the user program
● Via STEP 7 or HMI devices
● Via the Web server of the CPU
Reading I&M data via the user program
You have the following options for reading module I&M data in the user program:
● Via the instruction RDREC.
The data set structure for distributed modules accessible over PROFINET IO is described
in the section Data record structure for I&M data (Page 92).
● Using the instruction Get_IM_Data (only I&M0 data).
