9 FIRMWARE UPDATE FUNCTION
9.2 Update Using the Engineering Tool
Troubleshooting
If an error occurs, take corrective action according to the error code. (Page 782 List of error codes)
If the error cannot be judged by the error code, check the following items and troubleshoot the situation.
Error details Action
The firmware update function screen is not
displayed.
• Check that the communication route is connected to the built-in port of the CPU module (Ethernet (Ethernet
port direct connection/connection via hub)), and re-execute the update.
• Check whether the firmware version of the CPU module is compatible with the update using the engineering
tool. If the CPU module is not compatible, update the CPU module via an SD memory card.
The update file cannot be set. Check that the firmware update file downloaded from the Mitsubishi Electric FA website has been selected, and
re-execute the update.
The update is not performed even when
[Update] is pressed, and an error message
dialog is displayed.
• Check that the firmware update is not prohibited, and re-execute the update.
• Check whether or not the firmware update file of the CPU module or any intelligent function module remains in
the "$MELPRJ$" folder in the SD memory card. If there is an unnecessary firmware update file, delete the file.
• Check that the SD memory card is inserted in the CPU module.
• Check that the version of the firmware update file is not the same as the firmware version of the module to be
updated.
• Check that the remote reset setting is "Enable", and re-execute the update.
• Check that the firmware update file downloaded from the Mitsubishi Electric FA website has been selected,
and re-execute the update.
An SD memory card error occurs during
execution of the firmware update.
• Re-insert the SD memory card, and re-execute the update.
• Check that the SD memory card is not write-protected, and re-execute the update.
• Format the SD memory card, and re-execute the update.
If the same error still occurs after the above actions are taken, the SD memory card may have a hardware error.
Replace the SD memory card.
The error code 1910H occurs during
execution of the firmware update.
• Check whether or not the firmware update file of the CPU module or any intelligent function module not to be
updated remains in the "$MELPRJ$" folder in the SD memory card. If there is an unnecessary firmware update
file, delete the file.
• Format the SD memory card, and re-execute the update.
The error code 1911H occurs during
execution of the firmware update.
Check that the specified intelligent function module is correctly inserted, and re-execute the update.
The error code 3040H occurs during
execution of the firmware update.
• To execute the firmware update, an intelligent function module compatible with the new version is required.
Please consult your local Mitsubishi representative.
• Check that the selected firmware update file matches the model of the module to be updated.
The error code 3041H or 3042H occurs
during execution of the firmware update.
Check that the firmware update file downloaded from the Mitsubishi Electric FA website has been selected, and
re-execute the update.
A communication timeout occurs during
execution of the firmware update.
A communication timeout or a cable trouble may have occurred, or the PLC power is OFF or reset. Execute the
following operations.
(1) Turn the CPU module power OFF and ON, and wait until the ERR LED and RUN LED flash. If the LEDs do
not flash after 60 seconds, re-execute the firmware update.
(2) Turn the CPU module power OFF and ON again, and wait until the ERR LED and RUN LED turn off. After
this, turn the CPU module power OFF and ON again. Then, the firmware update will be completed, and the
module will start normally. If the ERR LED flashes and the RUN LED turns off, turn the CPU module power
OFF and ON again.
In the following cases, the intelligent function module may have a hardware error. Please consult your local
Mitsubishi representative.
• When the ERR LED flashes and the RUN LED turns off in (2), even after the CPU module power is turned OFF
and ON twice, if the ERR LED flashes and the RUN LED turns off
• When the RUN LED does not turn off after 60 seconds in (2)
The firmware update is completed
abnormally.
(1) Turn the CPU module power OFF and ON, and wait until the ERR LED and RUN LED turn off. If the LEDs do
not flash, re-execute the firmware update.
(2) Turn the CPU module power OFF and ON again. Then, the firmware update will be completed, and the
module will start normally. If the ERR LED flashes and the RUN LED turns off, turn the CPU module power
OFF and ON again.
In the following cases, the intelligent function module may have a hardware error. Please consult your local
Mitsubishi representative.
• When the ERR LED flashes and the RUN LED turns off in (2), even after the CPU module power is turned OFF
and ON twice, if the ERR LED flashes and the RUN LED turns off
• When the RUN LED does not turn off after 60 seconds in (2)
