13.10.1 Reading out and entering I&M data
I&M data
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 enclosure of the module, such as article number and
serial number.
• Maintenance data (I&M1, 2, 3): Plant-dependent information, e.g. installation location.
The maintenance data for the SIMATIC Drive Controller is created during configuration
and downloaded to the automation system/distributed I/O system.
The SIMATIC Drive Controller supports 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
• Via the user program
• Via STEP 7 or HMI devices
• Via the CPU web server
Procedure for reading I&M data via the user program
You have the following options for reading the I&M data of the modules in the user program:
• Using the RDREC instruction
The data record structure for the CPU as well as for distributed modules accessible via
PROFINET IO/PROFIBUS DP is described in Record structure for I&M data (Page 298).
• Using the Get_IM_Data instruction
Further information
The description of the instructions can be found in the STEP 7 online help.
