If the error is not cleared even after turning the Special I/O Unit Restart Bit ON
and then OFF again, then replace the Unit.
The following tables explain the probable causes of troubles that may occur, and
the countermeasures for dealing with them.
Probable Cause
The output is not set for being
used.
The output hold function is in
operation.
The conversion value is set outside
of the permissible range.
Probable Cause
The output signal range setting is
wrong.
The I/O specifications of the output
device do not match those of the
Analog Output Unit (e.g., input
signal range, input impedance).
The offset or gain is not adjusted.
Probable Cause
The output signals are being
affected by external noise.

Countermeasure
Set the output for being used.
Turn ON the Output Conversion
Enable Bit.
Set the data within the range.
Countermeasure
Correct the output signal range
setting.
Change the output device.
Adjust the offset or gain.
Countermeasure
Try changing the shielded cable
connection (e.g., the grounding at
the output device).
