Identification and maintenance data
7.7.1
Reading out and entering I&M data
I&M data
I&M identification data is information which is stored on the module either as read-only data
(I-data) or read/write data (M-data).
Identification data (I&M0):
Manufacturer information about the module that can only be read
and is in part also printed on the housing of the module, for example, article number and
serial number.
Maintenance data (I&M1, 2, 3):
Plant-dependent information, e.g. installation location.
Maintenance data is created during configuration and written to the module.
Note
The CPU supports identi
fication data (I&M0) only for the 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.
STEP 7 allows you to read the identification I&M data (see STEP 7 online help).
Options for reading out I&M data
● Via the user program
● Via STEP 7 or HMI devices
● Via the Web server of the CPU
Procedure for reading I&M data by means of the user program
To read the I&M data of the modules in the user program, use the RDREC instruction.
The data record structure for distributed modules accessible via PROFINET IO is described
in section Data record structure for I&M data (Page 89).
