Exception Handling - General Information

Introduction

The main view Exception handling serves for clear representation of the exceptions in the module structure (analogous to the Structure editor).

From the editor Exception handling you can view and define the following:

oExceptions for the MainMachine, for the module groups and for every individual module

oReactions for the MainMachine, for module groups and for every individual module

oGlobal reactions

oGlobal exception list (online, read-only view)

NOTE: In this editor you cannot modify the module structure (shift, add, delete modules, and so on). For this purpose, switch to the Structure editor.
