A-4 Change Tracking
Change Tracking is used to display and manage changes in the safety application data after the pin is
created.
Tracking information is property information in safety application data. The storage of the safety appli-
cation data settings at a given point in time is referred to as creating a pin.
It is primarily used for version management after the safety application data is debugged.

Project Menu.
The Change Tracking Tab Page is displayed.
The outer frames of the cells for each item are displayed in the following colors if a pin has not
