Description
A sequencer instruction (SQO, SQC,
SQL) length/position parameter is
greater than 255.
A BSR or BSL instruction length
parameter is greater than 2048 or an
FFU, FFL, LFU, LFL instruction length
parameter is greater than 128 (word
file) or greater than 64 (double word
file)
A COP or FLL instruction length
parameter references outside of the
entire data space.
A particular controller type was
selected in the user program
configuration, but did not match the
actual controller type.
A particular hardware type (AWA,
BWA, BXB) was selected in the user
program configuration, but did no
match the actual base.
The hardware minimum series
selected in the user program
configuration was greater than the
series on the actual hardware.
The required expansion I/O
terminator was removed.
The controller cannot communicate
with an expansion I/O module.
An expansion I/O module generated
an error.
The required expansion I/O
terminator was removed.
The controller cannot communicate
with an expansion I/O module.
Fault Recommended Action
Classification
Recoverable Correct the user program, then re-compile,
reload the program and enter the Run mode.
Recoverable Correct the user program or allocate more
data file space using the memory map, then
reload and Run.
• Correct the program to ensure that the
Recoverable
length and parameter do not point outside
of the data file space.
• Re-compile, reload the program and enter
the Run mode.
• Connect to the hardware that is specified
Non-User
in the user program, or
• Reconfigure the program to match the
attached hardware.
• Connect to the hardware that is specified
Non-User
in the user program, or
• Reconfigure the program to match the
attached hardware.
• Connect to the hardware that is specified
Non-User
in the user program, or
• Reconfigure the program to match the
attached hardware.
• Check the expansion I/O terminator on the
Non-Recoverable
last
I/O module.
• Cycle power.
• Check connections.
Non-Recoverable
• Check for a noise problem and be sure
proper grounding practices are used.
• Replace the module.
• Cycle power.
• Refer to the I/O Module Status (IOS) file.
Non-Recoverable
• Consult the documentation for your
specific I/O module to determine possible
causes of a module error.
• Check expansion I/O terminator on last I/O
Non-User
module.
• Cycle power.
• Check connections.
Non-User
• Check for a noise problem and be sure
proper grounding practices are used.
• Replace the module.
• Cycle power.
