Configuring the Distributed I/O (DP)
Overwriting *.GSD Files
To represent DP slaves STEP 7 uses device database (*.GSD) files and symbols
which are installed in STEP 7, meaning:
• They were installed automatically with STEP 7 or
• They were installed at a later date
When you install or import the files at a later date, the existing *.GSD files/symbols
are not completely deleted but are stored in the following backup directory:
\\Step7\S7data\Gsd\Bkp[No.],
where [No.] is a serial number which STEP 7 assigns automatically.
Restoring Overwritten *.GSD Files
To restore *.GSD files/symbols you overwrote accidentally, proceed as follows:
1. Select the menu command Options > Install GSD File.
2. In the following dialog box, navigate to the directory
\\Step7\S7data\Gsd\Bkp[No]. Make sure that you select the required backup
directory (use the Explorer to find the directory with the correct date/time).
3. Click the "Open" button.
