Error name Description and
cause
Double input A double input
discrepancy discrepancy was
detection error detected in a pair of
inputs (X0 and X1,
X2 and X3, ...).
Input dark test During an input dark
error test, test pulses
were not detected.
I/O data error An error was
detected in the I/O
data.
Action
• Match the ON timing of the
external power supply with the
ON timing of the module power
supply.
• Correct the parameter settings
of "Double input discrepancy
detection time".
• Review the connected devices
and wiring.
• When the connected devices
and wiring have no errors, there
may be an influence from noise
or a hardware failure. Take
measures to reduce noise.
• If the same error occurs again,
the module may be in failure.
Please consult your local
Mitsubishi representative.
• When "Double input discrepancy
auto recovery setting" is set to
"1: Used", the module will
recover from this error after the
double input discrepancy is
eliminated.
• Match the ON timing of the
external power supply with the
ON timing of the module power
supply.
• Correct the parameter settings
of "Input dark test pulse OFF
time" and "Number of pulse
output for input dark test".
• Review the connected devices
and wiring.
• When the connected devices
and wiring have no errors, there
may be an influence from noise
or a hardware failure. Take
measures to reduce noise.
• If the same error occurs again,
the module may be in failure.
