Reference Data Command (Tools Menu)

Select the menu command Tools > Options > Reference Data to open the STEP 7 "Displaying S7 Reference Data" application. You can use this application to debug your simulated program.

This menu command is only available when a STEP 7 symbol table has been attached to the simulated program. Use the menu command Tools > Options > Attach Symbols... to invoke a dialog box where you can choose the STEP 7 symbol table to be referenced (attached).
