Chapter 2 Replacement Considerations with ControlLogix 5580 and GuardLogix 5580 Systems
SD Card Behavior
The controller has changed some behaviors when loading a project from the
SD card into a controller. These changes facilitate a better workflow for easier
commissioning of brand new out of box controllers. All Logix 5000 controllers
ship from the factory with firmware revision 1.x.
With 5580 controllers, the Load Image setting On Uninitialized Memory is
available. This setting replaces the On Corrupt Memory setting that is available
with 5570 controllers.
The general behavior is the same for both settings. The only difference is the
controller behavior when it is in the out-of-box condition, as described in
Table 6
.
You can install an SD card that uses On Uninitialized Memory in an out-of the
box controller, that is, one that uses firmware revision 1.
x. In this case, at power-
up the image loads both the controller firmware and controller application.
When you use an SD card with an image in an out-of-box controller (firmware
revision 1.x), at power-up that controller updates its firmware to the revision
stored on the card. The update happens regardless of the Load Image setting
you made when you transferred the image to the SD card.
The On Power Up, and On Initialized Memory settings also load the
controller application into an out of box controller.
This table shows what happens at power-up when you insert an SD card that
contains an image into a 5580 controller.
