9.6 Identification and maintenance data
9.6.1 Reading out and entering I&M data
Introduction
Identification and maintenance data (I&M data) is data saved on the module as read-only
(I data) or read/write (M data) information.
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., part number and serial number.
Maintenance data (I&M1, 2, 3): system-specific information, e.g. the installation location.
Maintenance data for the S7-1500 are created during configuration and loaded into the
automation system.
All modules of the S7-1500 support identification data (I&M0 through 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
● via the user program
● via the CPU's display
● via the CPU's web server
● via STEP 7 or HMI devices
