Editing Your Safety
Application
The following rules apply to changing your safety application in RSLogix 5000
software:
• Only authorized, specially-trained personnel can make program edits.
These personnel should use all supervisory methods available, for example,
using the controller keyswitch and software password protections.
• When authorized, specially-trained personnel make program edits, they
assume the central safety responsibility while the changes are in progress.
These personnel must also maintain safe application operation.
• When editing online, you must use an alternate protection mechanism to
maintain the safety of the system.
• You must sufficiently document all program edits, including:
– authorization.
– impact analysis.
– execution.
– test information.
– revision information.
• If online edits exist only in the standard routines, those edits are not
required to be validated before returning to normal operation.
• You must make sure that changes to the standard routine, with respect to
timing and tag mapping, are acceptable to your safety application.
• You can edit the logic portion of your program while offline or online, as
described in the following sections.
