Using Symbol Files

Specifying the Use of Symbol Files

The PROFInet tool “SIMATIC iMap” creates a symbol file for the OPC server.
Read the documentation of SIMATIC iMap for information on creating a symbol
file.

Activity

You can define hierarchically structured symbolic names for all OPC variables and use them in
your OPC client programs. You can extract these symbols from a STEP 7 project.

You can open the Configuration Console from the Start menu (Start

NET

Configuration Console).

Select “Symbols” and select the symbol file you want to use (browse for the symbol file or
create a new one with “Edit List”).

Click the “Start” button to start the Symbol File Configurator.
