7.8 Digital Oscilloscope Errors
When digital oscilloscope errors occur
If an error occurs at the digital oscilloscope, the error detection special relay turns ON, the error code is stored in a special
register, and this appears in the Motion CPU error batch monitor in MT Developer2. The error is not displayed in the error
history. Furthermore, if a self-diagnosis error has occurred, sampling will not be possible. (The cause of this error is also not
detected.)
■Bit device
■Word device
When the communication load is heavy, while automatically reading the sampling result, the MT Developer2
digital oscilloscope may timeout with the dialogue "reading..." displayed, and cancel reading (communication
error). When this happens, the sampling result can be read manually by [Online] [Sampling Result File
Operation].
Digital oscilloscope error list
The following table shows the details and cause of errors occurring at the digital oscilloscope, and the corrective action for
those errors.
Monitor item Stored content Monitor value Refresh cycle Device No.
Sampling setting
Sampling error
Turns ON when sampling error occurs.
Turns OFF when the next sampling is started.
OFF: No error
ON: Error
Main cycle SM765
Monitor item Stored content Monitor value Refresh cycle Device No.
Sampling setting
digital oscilloscope error
cause
The error code for the sampling error is stored.
This is cleared to 0 when the next sampling is performed.
0: No error
Other than 0: Error
code
Main cycle SD769
Error code Error name Error details and cause Corrective action
0032H Outside settings data
storage range
A value outside the setting range for the "Sampling
settings storage target" was set when "Sampling
setting RUN request" is ON.
Set the "Sampling settings storage target" inside the
range.
0033H Settings file write error No settings file exists. Write the settings file again from the digital
oscilloscope.
0034H SD card unusable Sampling was started with no SD memory card
inserted, or with use of the SD memory card forcibly
stopped.
• Check whether the SD memory card has been
inserted.
• If use of the SD memory card has been forcibly
stopped, release the stop.
0035H SD memory card writing
not possible
The SD memory card is write protected. Release the SD memory card write protect.
0064H Settings file error There is an error in the settings file. Write the settings file again from the digital
oscilloscope.
0065H Settings file version not
supported
The settings file version is not supported. Check the versions compatible with the digital
oscilloscope, and write the settings file again.
0096H Sampling results output
error
The specified drive (memory) capacity or folder/file
configuration is wrong, and therefore it was not
possible to complete sampling results output.
Delete any unnecessary files, and secure sufficient
memory space.
