Identification and maintenance data

9.3.1 Reading out and entering I&M data
Introduction
I&M identification data is information which is stored on the I/O device either as read-only
data (I‑data) or read/write data (M‑data).
Identification data (I&M0): Manufacturer information on the I/O device that is read-only and
in some cases is also lasered on the I/O device housing, for example, article number, serial
number and firmware version.
Maintenance data (I&M1, 2, 3): Plant-dependent information, e.g. installation location.
Maintenance data is created during the configuration and written to the I/O device.
All modules of the ET 200eco PN M12‑L distributed I/O system support identification data and
maintenance 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 system
• Correcting errors in a system
With the I&M identification data, you have the option of clearly identifying I/O devices online.
In STEP 7, the identification data is displayed in the "Module status" and "Properties..." tabs
(see STEP 7 online help).
Options for reading out I&M data
You have the following options for reading the I&M data:
• Via the user program
• Via STEP 7 or HMI devices
Procedure for reading I&M data by means of the user program
To read the I&M data of the I/O devices in the user program, use the instruction "RDREC".
With third party software, the "read record" instruction may be named differently.
You can find more information in the "MultiFieldbus
(https://support.industry.siemens.com/cs/ww/en/view/109773209)" function manual.
Procedure for reading the I&M data using STEP 7
Requirement: An online connection to the I/O device must be available.
1. Select the I/O device in project tree under "Distributed I/O".
2. Select: IO device/DP slave > Online & Diagnostics > Identification & Maintenance.
