Testing the application or debugging the data

logi.CAD 3 provides the →perspective Application Testing for you to monitor and test your application loaded onto the PLC. You might know this possibility as debugging of data (in contrast to the control flow debugging).

How to open the perspective Application Testing:

• In menu Window, select Open Perspective and Application Testing.
