9.4 Non-Fatal Errors
Non-fatal errors are errors that may affect the control system but do not prevent the controller
for operating reliably. Non-fatal errors can be displayed using the programming software and by
examining designated Status Words.
The following table lists the system non-fatal errors that may occur and how to resolve them.
Error Cause Correction
Scan Overrun
(STW 1:14)
The designated fixed scan time
or upper limit is not sufficient to
execute the User Program. Increase the fixed scan time or upper
limit.
Reduce the analog scan time slices.
Reduce the number of task codes per
scan
I/O Base Failure
A remote base controller is not
responding. Ensure that the base is connected to
the I/O network and that the cable is
not defective.
Ensure that you have not duplicated a
base address.
Replace the remote base controller.
I/O Module Failure
(STW 1:12) An I/O module is reporting a
failure Use your programming software to
determine which module has failed.
Replace the module.
Too Many SF Modules
Installed
(STW 1:10) More than 16 Special Function
Modules have been installed. SF modules beyond 16 will not be
accessed. Remove excess SF
modules.
I/O Mismatch
The actual base configuration
does not match the I/O
configuration in the User
Program. Use STW 11- STW 26 to determine
which slots are mismatched.
Change the I/O configuration to match
the actual configuration.
Change the actual configuration to
match the I/O configuration.
SF Module Failure
(STW 1:12) A Special Function module is
not communicating properly
with the controller Determine which module is failing
using your programming software and
replace the module.
Password Disabled
(STW 1:5) A password exists but has been
disabled. This is only a warning.
TOD Clock Failure
(STW 1:8) Indicates that the time of day
clock is not operating properly. This is typically a hardware failure. If
you are using the TOD clock for
control, you will need to replace the
controller.
Battery Bad/Low
(STW 1:15) Indicates that the battery is not
operational or that it may soon
fail. Ensure that the battery switch is on.
Replace the battery.
RLL Program Error
(STW1:6) Indicates a general program
error See STW 200 for the error code
RLL Subroutine Stack
Overflow
(STW 1:7) Indicates a stack overflow has
occurred. Determine the number of the
subroutine that caused the error by
examining STW 163 and correct the
programming error.
Previous RLL Instruction
failed
(STW1:11) Indicates that the previous RLL
instruction failed to execute
properly due to a run time
parameter error. See Status Word 200 for more specific
information and correct the
programming error.
