Error name Description and
cause
External power An external power
supply voltage supply error was
error detected.
Parameter data An incorrect value
error or parameter data
out of the range is
set.
Parameter data The version
error (version mismatch of the
information) module used and
engineering tool
was detected.
Parameter data An incorrect value
error (wiring or parameter (wiring
selection of selection of input)
input) out of the range is
set.
Parameter data An incorrect value
error (input or parameter data
response time) out of the range is
set.
Action
• Match the ON timing of the
external power supply with the
ON timing of the module power
supply.
• Review the connected devices,
wiring, and voltage.
• There may be an influence from
noise of external wiring (such as
power supply part and I/O signal
part). Take measures to reduce
noise.
• If the same error occurs again,
the module may be in failure.
Please consult your local
Mitsubishi representative.
• Correct the module parameter
settings and module
configuration.
• When the parameters are set
again and the parameter setting
has succeeded, the module will
recover from this error.
• Review the version of the
engineering tool and that of the
master station.
• Check that the module version
set in the "Network
Configuration Settings" of the
engineering tool matches with
the version of actual module.
• When the parameter is set again
and the parameter setting has
succeeded, the module will
recover from this error.
• Correct the module parameter
settings (wiring selection of
input) and module configuration.
• When "Wiring selection of input"
Xn (n: even number) is set to "1:
Double wiring (NC/NC)", set the
same value for Xn+1.
• When the parameters are set
again and the parameter setting
has succeeded, the module will
recover from this error.
• Correct the module parameter
settings (input response time)
and module configuration.
• When "Wiring selection of input"
Xn (n: even number) is set to "1:
Double wiring (NC/NC)", set the
same value for Xn+1.
• Set the input response time so
that it is longer than the input
dark test pulse output time.
Input dark test pulse output time =
Pulse OFF time for the input dark
test  ((Number of pulse outputs
for the input dark test  2) - 1)
• When the parameters are set
again and the parameter setting
has succeeded, the module will
recover from this error.
