Change Controller Type in RSLogix 5000 Projects

Because safety controllers have special requirements and do not support certain
standard features, you must understand the behavior of the system when
changing the controller type from standard to safety or from safety to standard in
your RSLogix 5000 project. Changing controller type affects the following:

Supported features

Physical configuration of the project, that is the safety partner and Safety
I/O

Controller properties

Project components such as tasks, programs, routines, and tags

Safety Add-On Instructions

Changing from a Standard to
a Safety Controller

Upon confirmation of a change from a standard controller to a safety controller
project, safety components are created to meet the minimum requirements for a
safety controller:

The safety task is created only if the maximum number of downloadable
tasks has not been reached. The safety task is initialized with its default
values.

Safety components are created (that is safety task, safety program, and so
forth).

A time-based safety network number (SNN) is generated for the local
chassis.

Standard controller features that are not supported by the safety controller,
such as redundancy, are removed from the Controller Properties dialog
box (if they existed).
