Description
• Either an expansion I/O power
supply is configured in the user
program, but no power supply is
present, or
• an expansion I/O power supply is
configured in the user program
and a power supply is physically
present, but the types do not
match.
An expansion I/O object (i.e. cable,
power supply, or module) in the user
program I/O configuration is not the
same object type as is physically
present.
The first word of string data contains
a negative, zero, or value greater
than 82.
Fault Recommended Action
Classification
• Correct the user program to eliminate a
Non-User
power supply that is not present
• Re-compile, reload the program and enter
the Run mode, or
• With power removed, add the missing
power supply.
• Correct the user program I/O configuration
Non-User
so that the object types match the actual
configuration, and
• Re-compile, reload the program and enter
the Run mode. Or
• Correct the actual configuration to match
the user program I/O configuration.
• Cycle power.
Recoverable Check the first word of the string data
element for invalid values and correct the
data.
