The communication driver set in the Communication Setting and the communication
unit installed on the GOT do not match.
• Check whether the communication driver set in the Communication Setting is
correct.
• Check whether any incorrect communication unit has been installed on the GOT.
Turn the power of the PLC and GOT on again.
Units are mounted on the GOT exceeding the maximum number of mountable
units.Check the number of units, and remove unnecessary units.
Inactive channel No. has been set in the project data.
• Check whether any unnecessary channel No. has been set in the project data.
• Check whether channel Nos. set in the project data are set in the Communication
Settings.
Unit unusable for GOT is installed.
Remove the unusable unit.
Check if the extension units are securely mounted on the GOT.
Install the communication driver(s) again.
The voltage of the GOT built-in battery is decreased.
Replace the GOT built-in battery.
The dedicated GS is notifying that the backlight power on addition time has reached
the set time or more.
Please consult your local Mitsubishi service center or representative.
The GOT can be restored by executing the addition times reset function. The GOT
can also be restored by turning off the notification signal manually. In such a case,
turn it OFF after setting a value greater than the addition time.
The value that is input as clock data is out of the input enabled range.
In this case, the input value is not accepted.
Confirm the input range of the value to be input as clock data, and input the proper
value again.
The old file of different contents has been deleted and a new file has been created.
Note that the old file is deleted and the new file is created if the file of the same name
with different contents exists when creating files.
When the alarm settings (such as the number of alarm points and hierarchies) are
changed, alarm log files before the change are imported and alarms are collected
with the new settings.
Therefore, different alarms may be displayed before and after the alarm setting
change.
Delete alarm log files as necessary.
Unable to read the alarm log file saved by the different project.
Confirm the alarm log file and where to store the alarm log file.
The file specified for the file conversion does not exist.
Check the settings for specifying a file to be converted.
The capacity for the SRAM user area is insufficient.
Confirm the available memory in the SRAM user area.
The error may be caused by a failure in the GOT main unit.
Contact your local Mitsubishi representative.
Error in SRAM data due to battery voltage low, etc.
Confirm the battery status.
Confirm whether any file exists in the SD card or USB memory.
• Confirm whether image files in the SD card or USB memory are normal.
• Confirm whether any image file of invalid format is stored.
No font appropriate for the system language specified at the system language
