Description
The maximum number of expansion
I/O cables allowed was exceeded.
The maximum number of expansion
I/O power supplies allowed was
exceeded.
The maximum number of expansion
I/O modules allowed was exceeded.
An expansion I/O module could not
communicate at the baud rate
specified in the user program I/O
configuration.
• The expansion I/O configuration
in the user program did not match
the actual configuration, or
• The expansion I/O configuration
in the user program specified a
module, but one was not found,
or
• The expansion I/O module
configuration data size for a
module was greater than what
the module is capable of holding.
The number of input or output image
words configured in the user
program exceeds the image size in
the expansion I/O module.
An expansion I/O module generated
an error.
• Either an expansion I/O cable is
configured in the user program,
but no cable is present, or
• an expansion I/O cable is
configured in the user program
and a cable is physically present,
but the types do not match.
Fault Messages and Error Codes
Fault Recommended Action
Classification
• Reconfigure the expansion I/O system so
Non-User
that it has an allowable number of cables.
• Cycle power.
• Reconfigure the expansion I/O system so
Non-User
that it has the correct number of power
supplies.
• Reconfigure the expansion I/O system so
Non-User
that it has an allowable number of
modules.
• Cycle power.
• Change the baud rate in the user program
Non-User
I/O configuration, and
• Re-compile, reload the program and enter
the Run mode, or
• Replace the module.
• Cycle power.
• Either correct the user program I/O
Non-User
configuration to match the actual
configuration, or
• With power off, correct the actual I/O
configuration to match the user program
configuration.
• Correct the user program I/O configuration
Non-User
to reduce the number of input or output
words, and
• Re-compile, reload the program and enter
the Run mode.
• Refer to the I/O status file.
Non-User
• Consult the documentation for your
specific I/O module to determine possible
causes of a module error.
• Correct the user program to eliminate a
Non-User
cable that is not present
• Re-compile, reload the program and enter
the Run mode, or
• Add the missing cable.
• Cycle power.
