4.4.5 Symbol Editor

Symbols can be browsed through by using the VWOPC Agent. As soon as a connection to the

OPC server has been entered, it is possible to activate the symbol browser by entering “Edit →

Import Items” in the menu.

After selecting the project type or a file, the corresponding lists are filled with the variables. After

selecting the variables, these can be transferred directly to the OPC server by activating the button

“Übernehmen” (”Adopt”).

4.4.6 The VWBrowser tool – S7 project

The VWBrowser tool is a simplified OPC DA interface. In this case, only the interfaces necessary

for the import of items have been implemented:

• IOPCServer (only the method “GetStatus”)

• IOPCBrowseServerAddressSpace

• IOPCItemProperties

This makes it possible for all VisiWin development environments to import items directly from

the databank of the Step7 project.
