4.10 Error Messages and Corrective Action
Corrective action
• Insert a data storage without a format error in the
GOT.
• Close the SD card cover.
• Delete files in the data storage.
• Insert a data storage with a large capacity.
• Cancel the write-protect setting for the folder that
is used for the sequence program monitor (ladder)
in the data storage.
Exit the sequence program monitor (ladder), and
then start the function again.
Corrective action
• Check the line status between the GOT and the
PLC CPU, and make the GOT communicate with
the PLC CPU.
• Check if the PLC CPU supports the sequence
program monitor (ladder).
• Check the line status between the GOT and the
PLC CPU, and make the GOT communicate with
the PLC CPU.
• Check if the PLC CPU supports the sequence
program monitor (ladder).
Check the line status between the GOT and the PLC
CPU, and make the GOT communicate with the PLC
CPU.
• Check the communications between the GOT and
PLC CPU, and make sure that the GOT
communicates with the PLC CPU.
• Select the file after changing the message display
language to one which can display the file name in
the utility.
• Change the file name with GX Works2/GX
Developer.
• Turn off the system protect switch of the PLC CPU.
• Wait until the boot process of the PLC CPU is
completed.
Set the PLC CPU to the STOP status.
Format the target drive by using GX Works2/GX
Developer.
Check files in the specified drive of the PLC CPU.
Delete the specified file by using GX Works2/GX
Developer, and then create the file again.
• Access the file when other devices do not access
the connected PLC CPU.
• Access the file after QCPU completes the
transference from the program cache memory to
the program memory.
