Identification data

8.3.1 Reading out and entering I&M data
Introduction
I&M identification data is read-only (I data) or read/write (M data) information that is saved on
the module.
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, e.g., order number and serial
number.
Maintenance data (I&M 1, 2, 3): system-specific information, e.g. the installation location.
The maintenance data is created during the configuration and written to the module.
All modules of the ET 200MP support identification data (I&M0 to I&M3).
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.
You can read out the identification data with STEP 7 (see online help for STEP 7).
Options for reading out I&M data
● by means of the user program
● via STEP 7 or HMI devices
Procedure for reading I&M data by means of the user program
To read the modules' I&M data in the user program, use the "RDREC" instruction.
The record structure for distributed modules that are accessible by PROFINET IO is
described in the Record structure for I&M data (Page 82) chapter.
Procedure for reading I&M data via STEP 7
Requirement: There must be an online connection to the interface module.
1. In project navigation under "Distributed I/O" select the I/O device "IM 155-5 PN ST".
2. Select > I/O Device > Online & Diagnostics > Identification & Maintenance.
