Set Passwords for Safety-
locking and -unlocking
Safety-locking the controller helps protect safety control components from
modification. Only safety components, such as the safety task, safety programs,
safety routines, and safety tags are affected. Standard components are unaffected.
You can safety-lock or -unlock the controller project when online or offline.
The safety-lock and -unlock feature uses two separate passwords. Passwords are
optional.
TIP
You can use the Controller Properties dialog box to change the controller
from standard to safety or vice versa by clicking Change Controller.
However, standard and safety projects are substantially affected.
See Appendix
B, Change Controller Type in RSLogix 5000 Projects, for
details on the ramifications of changing controllers.
