Probable cause Countermeasure Page
The input device’s signal range
does not match the input signal
range for the relevant input number
at the Analog I/O Unit.
Check the specifications of the
input device, and match the settings
for the input signal ranges.
225
The offset and gain are not
adjusted.
Adjust the offset and gain. 265
When using the 4 mA to 20 mA
range, the voltage/current switch is
not turned ON.
Turn ON the voltage/current switch. 231, 238
The ratio conversion function is set
to be used, so the calculation
results are being monitored.
Correct the conversion settings. 282
Probable cause Countermeasure Page
The input signals are being affected
by external noise.
Change the shielded cable connec-
tion to the Unit’s COM terminal.
243
Insert a 0.01-µF to 0.1-µF ceramic
capacitor or film capacitor between
the input’s (+) and (–) terminals.

Try increasing the number of mean
value processing buffers.

Probable Cause Countermeasure Page
The output is not set for being used. Set the output to be used. 259
The output hold function is in opera-
tion.
Turn ON the Output Conversion
Enable Bit.
261
The conversion value is set outside
of the permissible range.
Set the data within the range. 227, 259
Probable Cause Countermeasure Page
The output signal range setting is
wrong.
Correct the output signal range set-
ting.
259
The I/O specifications of the output
device do not match those of the
Analog I/O Unit (e.g., input signal
range, input impedance).
Change the output device. 223
The offset or gain is not adjusted. Adjust the offset or gain. 265
The ratio conversion function is set
to be used.
Correct the conversion settings. 262
Probable Cause Countermeasure Page
The output signals are being
affected by external noise.
Try changing the shielded cable
connection (e.g., the grounding at
the output device).
