Description
• A fault routine number was
entered in the status file, number
(S:29), but either the fault routine
was not physically created, or
• the fault routine number was less
than 3 or greater than 255.
An indirect address reference in the
ladder program is outside of the
entire data file space.
An error occurred in the EII
configuration.
The JSR instruction nesting level
exceeded the controller memory
space.
The program contains an
instruction(s) that is not supported
by the controller.
A sequencer instruction length/
position parameter references
outside of the entire data file space.
The length/position parameter of a
BSL, BSR, FFL, FFU, LFL, or LFU
instruction references outside of the
entire data file space.
A negative value was loaded to a
timer preset or accumulator.
The program contains a Temporary
End (TND), Refresh (REF), or Service
Communication instruction in an
interrupt subroutine (STI, EII, HSC) or
user fault routine.
An invalid value is being used for a
PID instruction parameter.
An error occurred in the HSC
configuration.
An error occurred in the PTO
instruction configuration.
An error occurred in the PWM
instruction configuration.
Fault Messages and Error Codes
Fault Recommended Action
Classification
• Either clear the fault routine file number
Non-User
(S:29) in the status file, or
• create a fault routine for the file number
reference in the status file (S:29). The file
number must be greater than 2 and less
than 256.
Recoverable Correct the program to ensure that there are
no indirect references outside data file space.
Re-compile, reload the program and enter the
Run mode.
Recoverable See the Error Code in the EII Function File for
the specific error.
Non-User Correct the user program to reduce the
nesting levels used and to meet the
restrictions for the JSR instruction. Then
reload the program and Run.
• Modify the program so that all instructions
Non-User
are supported by the controller.
• Re-compile and reload the program and
enter the Run mode.
• Correct the program to ensure that the
Recoverable
length and position parameters do not
point outside data file space.
• Re-compile, reload the program and enter
the Run mode.
• Correct the program to ensure that the
Recoverable
length and position parameters do not
point outside of the data space.
• Re-compile, reload the program and enter
the Run mode.
• If the program is moving values to the
Recoverable
accumulated or preset word of a timer,
make certain these values are not
negative.
• Reload the program and enter the Run
mode.
• Correct the program.
Non-Recoverable
• Re-compile, reload the program and enter
the Run mode.
Recoverable See page 19-1, Process Control Instruction for
more information about the PID instruction.
Recoverable See the Error Code in the HSC Function File
for the specific error.
Recoverable or See the Error Code in the PTO Function File for
Non-User the specific error.
Recoverable or See the Error Code in the PWM Function File
Non-User for the specific error.
