Chapter 1 Store and load a project by using a memory card
When to load an image
You have several options for when (under what conditions) to load the project
into the user memory (RAM) of the controller.
If you want to load an image Then choose Notes
Whenever you turn on or cycle the chassis power On Power Up • During a power cycle, online changes, tag values, and network schedules
that you have not stored on the memory card are lost.
• Loading from a memory card may also change the firmware of the
controller. For more information, see Perform firmware updates on page
14 .
• You can use the Logix Designer application to load the project.
Whenever there is no project in the controller and you turn on
or cycle the chassis power On Corrupt Memory • For example, if the battery becomes discharged or the ESM is
disengaged and the controller loses power, the project is cleared from
memory. When power is restored, this load option loads the project back
into the controller.
• Loading from a memory card may also change the firmware of the
controller. For more information, see Perform firmware updates on page
14 .
• You can use the Logix Designer application to load the project.
Only through the Logix Designer application User Initiated
This table provides load option examples.
Example Description
Load Image = On Power Up
Load Mode = Program 1. You update the firmware of the controller to the desired revision.
2. You store the project for the controller on the memory card.
3. When you turn on power to the controller after installation, the project loads into the controller.
4. The controller remains in Program mode.
Load Image = On Corrupt Memory
Load = Run 1. You store the project for the controller on the memory card (the major and minor revisions of the
firmware in the controller match the major and minor revisions of the project on the memory card.)
2. If the battery discharges or the ESM is disengaged and power to the controller is interrupted, the project
is cleared from the controller memory.
3. When power is restored, the project automatically loads into the controller and the controller returns to
Run mode.
Load Image = On Power Up
Load Mode = Program
Revision ≥ 12.0 1. The controller fails.
2. You remove the memory card.
3. You replace the failed controller with a new controller.
4. You replace the memory card.
5. When you turn on the power, the firmware and project load into the controller. The controller remains
in Program mode.
Load Image = On Power Up
Load Image = Not applicable 1. You want to load a different project into your controller.
2. A memory card contains the desired project.
3. With the memory card installed in the controller, use the Logix Designer application to load the project
into the controller.
