Question: Export/Import of DP with _address power config

30.06.2026 16:18 by Daniele Urbini

I am trying to export a DP Type to modify it on Excel.
I need to change the _Address reference config.
I tried to right-click on the dpt, create template(1DP/line), but when I click it it just coninue to load for hours (the dpt contains only 4 dp and 1 master dp).
When using th ASCII manager, the export setting, works: I can open the .ascii file in excel withc the MaPara tool installed and it seems coherent, but when I modify the file and try to import it back in WinCC OA, the Logfile is opened and the info shown are only:
1, Manager Start ......
3, Trying to connect to (SYS:0 Data -num 0 COONN:1) ..........
4, Connected to (SYS: 0 Data -num 0 CONN: 1) ........
6, Initialization by Data Manager finished ...........
4, Connected to (SYS: 1 Event -num 0 CONN: 1) ..............
102, Waiting for user names/passwords
103, User names/passwords initialized
181, Closing connection to (SYS: 0 Data -num 0 CONN: 1)
181, Closing connection to (SYS: 0 Event -num 0 CONN: 1)
39, Connection lost, MAN: (SYS: 0 Data -num 0 CONN: 1), Connection closed
39, Connection lost, MAN: (SYS: 1 Event -num 0 CONN: 1), Connection closed
2, Manager Stop
This happens even if I export, then immediatly after import back the file.
I've also tried with an existing dpt, and a new dpt, but it is always the same.
when importing i have flagged the checkbox stating: Automatically update existing DP types

If you are using master datapoints and instances you have to check the first parameter for a line of values in the ASCII file. This only applies to files in ASCII format V3 and V4 (power config file formats).
With the first parameter you can define if the line shall be applied when importing the file. You have to set "M" for modify.
Please check which values are set in your ASCII file.
