This chapter explains the types of errors that may occur when the Q62DA-FG is used,
and how to troubleshoot such errors.
8.1 Error Code List
If an error occurs in Q62DA-FG while writing to or reading data from the PLC CPU, the
applicable error code is written to buffer memory address 19 (Un\G19).

10
The setting is outside the output range setting that
can be made by the intelligent function module switch
of the GX Developer.
indicates the incorrectly
specified channel number.
Reset to the correct parameter with GX Developer
parameter setting. (See Section 4.5.)
111 Module error at startup.
Turn the power ON and OFF again. If the error
occurs again, the module may be malfunctioning.
Contact the nearest distributor or branch office with a
description of the problem.
112
The value set to the intelligent function switch 5 is
other than 0.
Re-set the correct parameter value in the parameter
setting of GX Developer. (Refer to Section 4.5.)

The G.OGSTOR instruction was executed in the
offset/gain setting mode.
Do not execute the G.OGSTOR instruction in the
offset/gain setting mode.
162

• The G.OGSTOR instruction was executed
consecutively.
• At the time of offset/gain setting, a set value was
written to the E
2
PROM 26 or more times.
• Execute the G.OGSTOR instruction only once for
one module.
• At the time of offset/gain setting, write a set value
only once at one time.

The G.OGSTOR instruction was executed for the
model that differs from the model for which the
G.OGLOAD instruction had been executed.
Execute the G.OGLOAD and G.OGSTOR
instructions for the same model.
164
The value set to the G.OGLOAD instruction,
G.OGSTOR instruction or pass data classification
setting (buffer memory address 200: Un\G200) is
outside the range.
Set the value within the range.

The offset value is equal to or larger than the gain
value. indicates the channel number causing the
error.
Reset so that the offset value becomes smaller than
the gain value.
500
1
More than one channel was set at the same time
during offset/gain settings.
Set the correct value in buffer memory addresses 22
and 23 (Un\G22 and Un\G23).
60
2
The specified digital value is outside the valid range.
indicates the channel number where the error
occurred.
Set a value that is within the valid range.

1
The warning output upper/lower limit value setting is
outside the range -16384 to 16383.
indicates the channel number incorrectly set.
Correct the contents of the buffer memory addresses
86 to 89 (Un\G86 to 89) to within the range -16384 to
16383.
