How to Import Tag

The tags created in the Symbol Table in Step7-MicroWIN software can be imported to EasyBuilder (EBPro).

  1. Create Tags in Symbol Table

    In Step7-MicroWIN, open the Symbol Table and create the tags. Select all the tags, right-click, and copy them.
    Step 7-MicroWIN Symbol Table with three test tags listed: TestMD (MD0), TestBitM (M5.7), TestVW (VW20).
  2. Add Driver in EasyBuilder (EBPro)

    Launch EasyBuilder, add the Siemens S7-200 driver in the device list under System Parameter Settings, then click the Import Tag button.

  3. Paste Copied Tags

    Paste the tags copied in step 1 into the Paste dialog and click OK.
    EasyBuilder Paste dialog with three tag lines pasted from Step 7-MicroWIN: TestMD MD0, TestBitM M5.7, TestVW VW20.
  4. Select All Tags and Confirm

    Select all the tags in the Add Tags dialog and click OK.
    EasyBuilder Add Tags dialog listing TestBitM (Bit, M-57), TestMD (Word, MD-0), and TestVW (Word, VW-20) with all three checked for import.
  5. Verify Import Success

    If the import succeeds, a confirmation message window appears.
    EasyBuilder Pro success dialog confirming Import tag information successfully.
