D-4 Fault Messages and Error Codes
0016 STARTUP
PROTECTION FAULT The user fault routine was executed
at power-up, prior to the main ladder
program. Bit S:1/13 (Major Error
Halted) was not cleared at the end of
the User Fault Routine. The User
Fault Routine ran because bit S:1/9
was set at power-up. Recoverable
•
Either reset bit S:1/9 if this is consistent
with the application requirements, and
change the mode back to RUN, or
•
clear S:1/13, the Major Error Halted bit,
before the end of the User Fault Routine.
0017 NVRAM/MEMORY
MODULE USER
PROGRAM
MISMATCH Bit S:2/9 is set in the controller and
the memory module user program
does not match the controller user
program. Non-Recoverable Transfer the memory module program to the
controller and then change to Run mode.
0018 MEMORY MODULE
USER PROGRAM
INCOMPATIBLE WITH
OS The user program in the memory
module is incompatible with the OS. Non-User
•
Upgrade the OS using ControlFlash to be
compatible with the memory module.
•
Obtain a new memory module.
•
Contact your local Rockwell Automation
representative for more information about
available operating systems your
controller.
001A USER PROGRAM
INCOMPATIBLE WITH
OS AT POWER-UP The user program is incompatible
with the OS. Non-User
•
Upgrade the OS using ControlFlash.
•

representative for more information about
available operating systems your
controller.
0020 MINOR ERROR AT
END-OF-SCAN
DETECTED A minor fault bit (bits 0-7) in S:5 was
set at the end of scan. Recoverable
•
Correct the instruction logic causing the
error.
•
Enter the status file display in your
programming software and clear the fault.
•
Enter the Run mode.
0021 EXPANSION POWER
FAIL (EPF)
(MicroLogix 1500 only) A power failure is present on the
expansion I/O bank.
This error code is present only when
the controller is powered, and power
is not applied to the expansion I/O
bank. This is a self-clearing error
code. When power is re-applied to
the expansion I/O bank, the fault is
cleared. See Important note below. Non-User Re-apply power to the expansion I/O bank.
See Important note below.
IMPORTANT
If this fault occurs while the system is in the RUN mode, the controller faults. When expansion I/O
power is restored, the controller clears the fault and re-enters the RUN mode.
If you change the mode switch while this fault is present, the controller may not re-enter the RUN mode
when expansion I/O power is restored.
If an EPF condition is present and expansion I/O power is OK, toggle the mode switch to PROGRAM and
then to RUN. The fault should clear and the controller enters the RUN mode.
0022 WATCHDOG TIMER
EXPIRED, SEE S:3 The program scan time exceeded the
watchdog timeout value (S:3H). Non-Recoverable
•
Determine if the program is caught in a
loop and correct the problem.
•
Increase the watchdog timeout value in
the status file.
0023 STI ERROR An error occurred in the STI
configuration. Recoverable See the Error Code in the STI Function File for
the specific error.
