Procedure for input of maintenance data using STEP 7
The default module name is assigned by STEP 7. You have the option to enter the following
data:
• Plant designation (I&M1)
• Location identifier (I&M1)
• Installation date (I&M2)
• Additional information (I&M3)
• Signature (I&M4), only for PROFINET
To enter the data, follow these steps:
1. In the device view of the STEP 7 hardware network editor, select the interface module, for
example.
2. In the properties under "General", select the "Identification & Maintenance" area and enter
the data.
During the loading of the hardware configuration, the I&M data are also loaded.
