When there is an error in the instruction construction, target device or target device number range and an
error occurs while operation is executed, the following flag turns ON and the error information is stored.

*1.

When an error occurs in a step up to the step No. 32767 in the FX

3U

/FX

3UC

 PLC, you can check the

error occurrence step also in D8069 (16 bits).

• When an operation error has occurred, M8067 turns ON, D8067 stores the operation error code, and the 

specified device (shown in the table above) stores the error occurrence step.

• When another error occurs in another step, the stored data is updated in turn to the error code and step 

number of the new error.  (These devices are set to OFF when errors are cleared.)

• When the PLC mode changes from STOP to RUN, these devices are cleared instantaneously, and then 

turn ON again if errors have not been cleared.

*2.

When an error occurs in a step up to the step No. 32767 in the FX

3U

/FX

3UC

 PLC, you can check the

error occurrence step also in D8068 (16 bits).

• When an operation error has occurred, M8068 turns ON, and the device shown in the table above stores 

the error occurrence step.

• Even if another error occurs in another step, the stored data is not updated and remains held until these 

devices are forcibly set to OFF or until the power is turned OFF.
