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:
• Safety I/O modules 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 connections
remaining.
• Instructions may still reference modules that have been deleted and will
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 will 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.
When you change from one safety controller type to another, the class of tags,
routines, and programs remains unaltered. Any I/O modules that are no longer
compatible with the target controller are deleted.
EXAMPLE 1768 Compact I/O™ modules are not compatible in a (1769) Compact
GuardLogix® 5370 controller system.
The representation of the safety partner is updated to appear appropriately for
the target controller in these cases:
• The safety partner is created in slot x (primary slot + 1) when changing
from a Compact GuardLogix 5370 to a GuardLogix 5570 controller.
• When changing to a Compact GuardLogix 5370 controller from a
GuardLogix 5570 controller, the safety partner is removed because it is
internal to the Compact GuardLogix controller.
