Status Indicators Appendix A
General Status Messages
The messages described in Table 52 are typically indicated upon powerup,
powerdown, and while the controller is running. These messages indicate the
status of the controller and the ESM.
Table 52 - General Status Display
Message Interpretation
No message is indicated The controller is off, or a major nonrecoverable fault (MNRF) has occurred.
Check the OK indicator to determine if the controller is powered and determine the state of the controller.
TEST Power-up tests are being conducted by the controller.
PASS Power-up tests have been successfully completed.
SAVE A project is being saved to the SD card at powerdown. You can also view the SD Indicator (see page
151) for additional status information.
Let the save complete before removing the SD card or disconnecting power.
LOAD A project is being loaded from the SD card at controller powerup. You can also view the SD Indicator (see page 151) for additional status information.
Let the load complete before removing the SD card, removing the ESM module, or disconnecting power.
UPDT A firmware update is being conducted from the SD card upon powerup. You can also view the SD Indicator (see page 151) for additional status
information.
If you do not want the firmware to update upon powerup, change the controller’s Load Image property.
CHRG The capacitor-based ESM is being charged.
1756-L7x/X The controller catalog number and series.
Rev XX.xxx The major and minor revision of the controller’s firmware.
No Project No project is loaded on the controller.
To load a project, use the Logix Designer application to download the project to the controller, or use an SD card to load a project to the controller.
Project Name The name of the project that is currently loaded on the controller. The name indicated is based on the project name specified in the Logix Designer
application.
BUSY The I/O devices associated with the controller are not yet fully-powered.
Allow time for powerup and I/O device self-testing.
Corrupt Certificate
Received
The security certificate associated with the firmware is corrupted.

and download the firmware revision you are trying to upgrade to. Replace the firmware revision you
have previously installed with that posted on the Technical Support website.
Corrupt Image Received The firmware file is corrupted.
Go to
http://www.rockwellautomation.com/support/
and download the firmware revision you are trying to upgrade to. Replace the firmware revision you
have previously installed with that posted on the Technical Support website.
ESM Not Present An ESM is not present and the controller cannot save the application at powerdown.
Insert a compatible ESM, and, if a capacitor-based ESM is used, do not remove power until the ESM is charged.
ESM Incompatible The ESM is incompatible with the memory size of the controller.
Replace the incompatible ESM with a compatible ESM.
ESM Hardware Failure A failure with the ESM has occurred and the controller is incapable of saving of the program in the event of a powerdown.
Replace the ESM before removing power to the controller so the controller program is saved.
ESM Energy Low The capacitor-based ESM does not have sufficient energy to enable the controller to save the program in the event of a powerdown.
Replace the ESM.
ESM Charging The capacitor-based ESM is charging.
Do not remove power until charging is complete.
Flash in Progress A firmware update initiated via ControlFLASH™ or AutoFlash software is in progress.
Allow the firmware update to complete without interruption.
Firmware Installation
Required
The controller is using boot firmware (that is revision 1.xxx) and requires a firmware update.
Update the controller firmware.
SD Card Locked An SD card that is locked is installed.
