Table 38 - Options for Loading a Project
If you want to load the project
Whenever you turn on or cycle
power
Whenever there is no project in the
controller and you turn on or cycle
power
Only through RSLogix 5000®
software
You have several options for when (under what conditions) to load a project
into the user memory of the controller.
Then select this

option Notes
On Power Up • During a power cycle, you lose any online changes, tag values, and network schedule that you have not stored in
the nonvolatile memory.
• The controller loads the stored project and firmware at every power-up regardless of the firmware or application
on the controller. The load occurs whether or not the controller is safety-locked or has a safety task signature.
• You can always use the programming software to load the project.
On Uninitialized • The controller updates the firmware on the controller, if required. The application stored in nonvolatile memory is
Memory also loaded and the controller enters the selected mode, either Program or Run.
• You can always use the programming software to load the project.
User Initiated • If the controller type as well as the major and minor revisions of the project in nonvolatile memory match the
controller type and major and minor revisions of the controller, you can initiate a load, regardless of the Safety Task
status.
• Loading a project to a safety-locked controller is allowed only when the safety task signature of the project stored
in nonvolatile memory matches the project on the controller.
• If the signatures do not match or the controller is safety-locked without a safety task signature, you are prompted
to first unlock the controller.
IMPORTANT: When you unlock the controller and initiate a load from nonvolatile memory, the safety-lock status,
passwords, and safety task signature are set to the values contained in nonvolatile memory once the load is
complete.
• If the firmware on the controller matches the revision in nonvolatile memory, the internal safety partner firmware
is updated, if required, the application stored in nonvolatile memory is loaded so that the Safety Task status
becomes Safety Task Operable and the controller enters the selected mode, either Program or Run.
Follow these steps to use the application to load the project from an SD card.
1. Go online with the controller.
2. Put the controller in Program mode, that is, Remote Program or
Program.
3. On the Online tool bar, click the controller properties icon.
4. Click the Nonvolatile Memory tab.
