5. Move the original project archive file out of its current directory. You
can delete this file or store it in an archival location. This step is required
because if the Studio 5000 Logix Designer application finds the
projectname.ACD in this directory, it correlates it with the controller
project and does not perform an actual upload.
6. With the controller still in Program mode, upload the project from the
controller.
7. Save the uploaded project as Onlineprojectname.ACD, where
'projectname' is the name of your project.
8. Answer Yes to the Upload Tag Values prompt.
9. Use the Studio 5000 Logix Designer Program Compare utility to
perform these comparisons:
• Compare all properties of the GuardLogix controller and CIP Safety
I/O devices.
• Compare all properties of the safety task, safety programs, and safety
routines.
• Compare all logic in the safety routines.
10. Verify that all controller and I/O configuration fulfills the requirements
of your application specification.
Safety Assessment
An independent, third-party review of the safety system may be required
before the system is approved for operation. An independent, third-party
certification may be required for IEC 61508 SIL 2 or SIL 3 levels.
Lock the Controller
We recommend that you safety-lock the GuardLogix controller to help protect
safety control components from modification. However, safety-locking the
controller is not a requirement for SIL 2 or SIL 3. The safety-lock feature
applies only to safety components, such as the safety task, safety programs,
safety routines, safety tags, safety Add-On Instructions, safety I/O, and safety
signature. However, safety-locking alone does not satisfy SIL 2 or SIL 3
requirements.
