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-dependent information, e.g. installation location.
Maintenance data is created during configuration and downloaded to the module.
All modules of the ET 200SP distributed I/O system 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.
STEP 7 allows you to read the identification I&M data (see STEP 7 online help).
Note
The BusAdapter and the interface module IM 155-6 PN HF support the identification data
I&M0 to I&M4 (signature).
Options for reading out I&M data
● Via the user program
● Via STEP 7 or HMI devices
● Via the CPU web server
