Type concept

The type concept allows the creation of standardized automation functions that you
can use in several plants or machines. The type concept supports you with
versioning and updating functions.
You can use types from the library in the user program. This offers the following
advantages:
Advantages
Central update of all usage locations in the project
Unwanted modifications of usage locations of types are not possible.
The system guarantees that types always remain consistent by hindering
unwanted delete operations.
If a type is deleted, all usage locations in the user program are deleted.
Properties
By using types you can make the changes centrally and update them in the
complete project.

Differences for typifiable objects for controller and HMI

There are system-related differences between the typifiable objects for controllers
and HMI:

Subordinate control elements are typified.
Subordinate control elements are
instanced.
Control elements are edited in a test
environment.
