Hello, I am working on developing an application that needs to import symbols from a Siemens S7P project but I am getting a bit confused with the s7p project folder structure. Are there any documentation anywhere that would explain the dbf files in the project folders?? Any help will be very much appretiated. What I observed so far is that the starting should be. Hrs s7resoff.dbf.

An s7 file extension is related to the Sibelius, a music composing program. An s7 file contains music notation.

I am guessing I need to link the information obtained from that file to another file somewhere and so on but I still have no clue where to go next. As far as I now, there is no an easy way to get symbols from dbf files.

But, if you open your project in the Simatic Manager and open symbols (symbol table) in Symbol Editor, you can select all symbols ( Edit / Select / All or Ctrl_A) then copy (Edit/Copy or Ctrl_c) the selection to the clipboard. After that you can paste it from the clipboard into some spreadsheet. You'll get something like this: [IMG]file:///C:/DOCUME%7E1/guro/LOCALS%7E1/Temp/moz-screenshot.png[/IMG] LL12ks22 M 245.3 BOOL description LL12ks23 M 245.4 BOOL description LL12ks24 M 245.5 BOOL description I hope there is a way your application can use data from the spreadsheet. Hi, I figured out some details of the dBase structures of a Step7 project, but it seems all very complex and confusing.

Nevertheless I got how to get the symbolic table of a S7-Program. I use Perl with a dBase module to read out the database files. Then you can use standard SQL queries to walk through the database.

# List S7-Program folders: SELECT NAME, ID FROM S7RESOFF # Choose the ID (=xxx) of the program-folder and # get the link ID from YLNKLIST SELECT SOI FROM YLNKLIST WHERE TOI = xxx # The result (yyy) is the linkage between SYMLISTS and S7RESOFF. # Get the subfolder of symbolic table SELECT _DBPATH FROM SYMLISTS WHERE _ID = yyy # you get the subfoldername of the symbolic file ( YDBs zzzz SYMLIST.DBF) # then read the symbolic table Step7-Manager-like with SELECT _SKZ, _OPHIST, _COMMENT FROM SYMLIST. Thank you guys for all the information.

I think the information about s7p files in that thread is more than the total of what I found in any other forums. Please reply if you have any more info about those files. What I am doing is some devolopment in an OPC server that connects to the siemens PLCs and I am trying to add the feature to read the s7p files same as other applications that connect to the PLC.

Do you know an OPC-Server which reads the Step 7 project files? Or do you mean the PLC 'browsing' you can do with the Simatic.Net OPC Server?

I meant the browsing and then importing the symbols. The OPC server that I encountered who does that is the siemens INAT OPC server OK, I just tested the trial version. I did a little research on the Step7 dBase structures:-) I'm able to read the symbolic table, the list of blocks in the project and the database structures. The absolut adresses in datablocks you have to calculate yourself.

Then you have to solve UDTs, arrays and so on. I think it will take some time to figure this all out, but it's possible. All you need you will find in the dBase files. Take a free dBase fileviewer like 'DBF Viewer', or just use MS-Access (MS-Access 2000 was possible to load dBase files). Interesting files for your project maybe S7RESOFF.DBF, YLNKLIST.DBF, SUBBLK.DBF, BAUSTEIN.DBF, SYMLIST.DBF.
