Fault Messages
If the controller displays a fault, these messages can be indicated on the status
display.
No Project
No project is loaded on the controller.
To load a project, do one of the following:
• Use Logix Designer application to download the project to the controller
• Use a SD card to load a project to the controller
Project Name
The name of the project that is currently loaded on the controller.
BUSY
The I/O modules that are associated with the controller are not yet fully powered.
Allow time for powerup and I/O module self-testing.
Corrupt Certificate
Received
The security certificate that is associated with the firmware is corrupted.
Go to
and download the firmware revision you are trying to upgrade to. Replace the firmware revision that
you have previously installed with that posted on the Technical Support website.
Corrupt Image Received
The firmware file is corrupted.
Go to
and download the firmware revision you are trying to upgrade to. Replace the firmware revision that
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 using a capacitor-based ESM, 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 upgrade initiated via ControlFLASH or AutoFlash utilities is in progress.
Allow the firmware upgrade to complete without interruption.
Firmware Installation
Required
The controller is using boot firmware (that is revision 1.xxx) and requires a firmware upgrade.
Upgrade controller firmware.
SD Card Locked
An SD card that is locked is installed.

Major Fault TXX:CXX message
A major fault of Type XX and Code XX has been detected.
For example, if the status display indicates Major Fault T04:C42 Invalid JMP Target, a JMP instruction is programmed to jump to an invalid
LBL instruction.
For details about major recoverable faults, see the Logix5000 Major, Minor, and I/O Fault Codes Programming Manual, publication
.
I/O Fault Local:X #XXXX message
An I/O fault has occurred on a module in the local chassis. The slot number and fault code are indicated along with a brief description.
For example, I/O Fault Local:3 #0107 Connection Not Found indicates that a connection to the local I/O module in slot three is not open.
Take corrective action specific to the type of fault indicated.
For details about each I/O fault code, see the Logix5000 Major, Minor, and I/O Fault Codes Programming Manual, publicat
