CHAPTER8 TROUBLESHOOTING

This chapter describes the errors which may occur during the use of the Q68RD3-G and 
troubleshooting.

8.1

Error Code List

If an error occurs when data is written to/read from the programmable controller CPU, the 
Q68RD3-G writes the corresponding error code to the buffer memory address (Un\G19).
Errors are classified into two levels: moderate (module error) and minor (module warning).
When a moderate error occurs, conversion processing is not performed.
When a minor error occurs, conversion processing is performed with the settings that the 
system operated normally last time.

10

Moderate

A value other than "0

H

" to "5

H

", or "8

H

" is set to the 

measurement range setting in the intelligent function 
module switch setting.

 indicates the error channel number.

Set a correct parameter value in the parameter setting 
of GX Developer. (Refer to Section 4.5.)

111

Moderate A hardware error of the module

Turn the power supply OFF, then ON again. If the same 
error occurs, the module may have failed. Please 
consult your local Mitsubishi representative.

112

Moderate

The setting value of the intelligent function module switch 
5 is other than "0".

Set "0" for the intelligent function module switch 5 in the 
parameter setting of GX Developer. (Refer to Section 
4.5.)

120

*1

Moderate

An invalid value is set in the offset/gain setting.
The error channel number cannot be identified.

Perform the offset/gain setting again for all of the 
channels that use the user range setting.
If the same error occurs, the module may have failed. 
Please consult your local Mitsubishi representative.

12

*1

Moderate

An invalid value is set in the offset/gain setting.

 indicates the error channel number.

Perform the offset/gain setting again for the error 
channel.
If the same error occurs, the module may have failed. 
Please consult your local Mitsubishi representative.

161

*2

Minor

The G(P).OGSTOR instruction was executed in the offset/
gain setting mode.

Do not execute the G(P).OGSTOR instruction in the 
offset/gain setting mode.

162

*1

Minor

•The G(P).OGSTOR instruction was executed 

consecutively.

•At the time of offset/gain setting, setting values were 

written to the flash memory 26 times or more.

•Execute the G(P).OGSTOR instruction only once per 

module.

•At the time of offset/gain setting, write setting values 

only once at a time.

163

*1

Minor

•The G(P).OGSTOR instruction was executed for the 

model that differs from the model for which the 
G(P).OGLOAD instruction had been executed.

•The G(P).OGSTOR instruction had been executed before 

the G(P).OGLOAD instruction was executed.

•Execute the G(P).OGLOAD and G(P).OGSTOR 

instructions for the same model.

•Execute the G(P).OGLOAD instruction first, then 

G(P).OGSTOR instruction.

*1

Minor

The average time setting value set in Un\G1 to Un\G8 is 
outside the range of 1280 to 5000ms.

 indicates the error channel number.

Re-set the average time setting value within the range 
of 1280 to 5000ms.

30

*1

Minor

The average count setting value set in Un\G1 to Un\G8 is 
outside the range of 4 to 500 times.

 indicates the error channel number.

Re-set the average count setting value within the range 
of 4 to 500 times.
