Upon confirmation of a change from a safety controller project to a standard
controller, some components are changed and others are deleted, as described
below:
• The safety partner is deleted from the I/O chassis.
• Safety I/O devices and their tags are deleted.
• The safety task, programs, and routines are changed to a standard task,
programs, and routines.
• All safety tags, except safety consume tags, are changed to standard tags.
Safety consume tags are deleted.
• Safety tag mappings are deleted.
• The safety network number (SNN) is deleted.
• Safety-lock and -unlock passwords are deleted.
• If the standard controller supports features that were not available to the
safety controller, those new features are visible in the Controller
Properties dialog box.
TIP Peer safety controllers are not deleted, even if they have no
• Instructions can still reference modules that have been deleted and can
produce verification errors.
• Consumed tags are deleted when the producing module is deleted.
• As a result of the above changes to the system, safety-specific
instructions and safety I/O tags do not verify.
If the safety controller project contains safety Add-On Instructions, you must
remove them from the project or change their class to standard before changing
the controller type.
