Programming Restrictions
Restrictions limiting the availability of some menu items and features (that is,
cut, paste, delete, search and replace) are imposed by the Logix Designer
application to help protect safety components from being modified whenever
the following is true:
• The controller is safety-locked.
• A safety task signature exists.
• Safety faults are present.
• Safety status is as follows:
–Partner missing
– Partner unavailable
– Hardware incompatible
– Firmware incompatible
If even one of these conditions apply, you cannot do the following:
• Create or modify safety objects, including safety programs, safety
routines, safety tags, safety Add-on Instructions, and safety I/O devices.
• Apply forces to safety tags.
•Create new safety tag mappings.
•Modify or delete tag mappings.
• Modify or delete user-defined data types that are used by safety tags.
• Modify the controller name, description, chassis type, slot, and safety
network number.
• Modify or delete the safety task signature, when safety-locked.
IMPORTANT The scan times of the safety task and safety programs can be reset
when online.
