Uncorrectable Internal
RAM Sweep Error
Test of RAM location where the
controller’s Application Image
executes detected an uncorrectable
bit error. Possible hardware failure
which may affect controller operation.
Replace the controller module and
return faulty module to the factory.
Corrected Internal RAM
Sweep Error
Test of RAM location where the
controller’s Application Image
executes detected (and corrected) a
number of bit errors that exceeded
the acceptable threshold. Possible

controller operation.
Replace the controller module and
return faulty module to the factory.
Uncorrectable User
RAM Sweep Error
Test of RAM location where the
controller’s control strategies and
states are maintained detected an
uncorrectable bit error. Possible
hardware failure which may affect
controller operation.
Replace the controller module and
return faulty module to the factory.
Corrected User RAM
Sweep Error
Test of RAM location where the
controller’s control strategies and
states are maintained detected (and
corrected) a number of bit errors that
exceeded the acceptable threshold.
Possible hardware failure which may
affect controller operation.
Replace the controller module and
return faulty module to the factory.
IOLink(1) Soft Fail Error
Indicates that the IO LINK 1 interface
is in soft fail.
View the Main tab of the
configuration form for the IOLINK
block for soft failures specific to the
IO LINK interface. See IOLINK
block soft failures for description
and corrective actions.
IOLink(2) Soft Fail Error
Indicates that the IO LINK 2 interface
is in soft fail.
View the Main tab of the
configuration form for the IOLINK
block for soft failures specific to the
IO LINK interface. See IOLINK
