Create an Assignment list-type export file (*.SEQ) via menu option Table Export. Correct the *.SEQ file (with Open Notepad, for example) as follows: delete all the lines in which you have declared no variables or DBs. Open the Dynamic Wizard window in the Graphics Designer. You will find the Import S7 S5- ZULI wizard under Import functions. Specify the import file and WinCC connection in the following dialog (see Fig. 1). You can drag drop this from the WinCC Explorer to the Dynamic Wizard (connection properties). Fig. 1: Specifying the name of the process connection in the Dynamic Wizard.Fig. 2: Name of the process connection in the WinCC Explorer. Note 1:N.B. You may only specify the symbolic names for the DBs in the symbol table. The symbol table does not contain any of the tags which you have declared in a DB. Consequently, the tags, which are in a DB, may not be imported to WinCC via the *.SEQ file either. However, the data may also be added manually.Write the DB tags, which you wish to import, directly under the declared DB. The wizard assigns all the data words included to the current DB until either a new DB is declared or an input/output or memory marker appears. Before: M 100.0 Memory marker MW 102 Memory word DB 1 Data block E 0.0 Input A 4.0 Output word After: M 100.0 Memory marker MW 102 Memory word DB 1 Data block DW 0 Data word_zero E 0.0 Input A 4.0 Output word Note 2:When using STEP 7 symbols directly in WinCC, pay attention to the section on Integration into the SIMATIC environment in the WinCC Information System for WinCC V5
