times — were set according to Chapter 6.

To view the fault recording data on a screen, one of the programs SIGRA

Comtrade Viewer (included with SIMATIC Manager) is needed. Do the following:

Double click on 2VFLOORJUDSKLF 5HFRUGV (Figure 7-2) to view the folder

• Vector diagrams

• Circle diagrams
