Rockwell Automation Logix5000 Controllers Major, Minor, and I/O Faults Programming Manual - Manual (Page 29)

Major faults Chapter 1
Example: Create a User-Defined Major Fault
When Tag_1.0 = 1, execution jumps to name_of_fault_routine. A major fault
occurs and the controller enters the faulted mode. Outputs go to the faulted state.
The Controller Properties dialog box, Major Faults tab, displays the code 999.
The type and code correspond to the type and code displayed in the following
locations.
• Controller Properties dialog box, Major Faults tab
• Program object, MajorFaultRecord attribute
Type Code Cause Recovery Method
1 1 The controller powered on in Run mode. Run the power-loss handler.
1 16 I/O communication configuration fault detected.
(CompactLogix 1768-L4x controllers only.)
Reconfigure the number of communication modules on the 1768 bus side of the
controller.
•
1768-L43 has a maximum of two modules.
• 1768-L45 has a maximum of four modules that can include up to:
− Four Sercos modules.
− Two NetLinx communication modules.
1 40 If the controller uses a battery, the battery does not contain
enough charge to save the user program on power-down.
If the controller uses an ESM (Energy Storage Module), the ESM
does not contain enough charge to save the user program on
power-down.
For controllers that use a battery, replace the battery.
For controllers that use an ESM (Energy Storage Module):
•
Allow the ESM to fully charge before powering down the controller.
• Replace the ESM if the ESM is removable, or replace the controller if the ESM is not
removable.
• If the problem persists, contact Rockwell Automation Technical Support.
