Updating the Controller Firmware by SD Card
The Modicon M262 Logic/Motion Controller accepts only SD cards formatted in FAT or FAT32.
The SD card must have a label. To add a label:
1.Insert the SD card in your PC.
2.Right-click on the drive in Windows Explorer.
3.Choose Properties.

UNINTENDED EQUIPMENT OPERATION |
|
oYou must have operational knowledge of your machine or process before connecting this device to your controller. oEnsure that guards are in place so that any potential unintended equipment operation will not cause injury to personnel or damage to equipment. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
When an SD card is inserted into the SD card slot of the controller, the firmware searches and executes the script contained in the SD card (/sys/cmd/Script.cmd).
Performing a firmware update deletes the current application program in the device, including the Boot Application in Flash memory.
|
NOTICE |
|
LOSS OF APPLICATION DATA |
|
oPerform a backup of the application program to the hard disk of the PC before attempting a firmware update. oRestore the application program to the device after a successful firmware update. |
|
Failure to follow these instructions can result in equipment damage. |
If you remove power to the device, or there is a power outage or communication interruption during the transfer of the application, your device may become inoperative. If a communication interruption or a power outage occurs, reattempt the transfer. If there is a power outage or communication interruption during a firmware update, or if an invalid firmware is used, your device will become inoperative. In this case, use a valid firmware and reattempt the firmware update.
|
NOTICE |
|
INOPERABLE EQUIPMENT |
|
oDo not interrupt the transfer of the application program or a firmware change once the transfer has begun. oRe-initiate the transfer if the transfer is interrupted for any reason. oDo not attempt to place the device into service until the file transfer has completed successfully. |
|
Failure to follow these instructions can result in equipment damage. |
The serial line ports of your controller are configured for the Machine Expert protocol by default when new or when you update the controller firmware. The Machine Expert protocol is incompatible with that of other protocols such as Modbus Serial Line. Connecting a new controller to, or updating the firmware of a controller connected to, an active Modbus configured serial line can cause the other devices on the serial line to stop communicating. Make sure that the controller is not connected to an active Modbus serial line network before first downloading a valid application having the concerned port or ports properly configured for the intended protocol.
|
NOTICE |
|
INTERRUPTION OF SERIAL LINE COMMUNICATIONS |
|
Be sure that your application has the serial line ports properly configured for Modbus before physically connecting the controller to an operational Modbus Serial Line network. |
|
Failure to follow these instructions can result in equipment damage. |

Step |
Action |
|---|---|
|
1 |
Download the firmware updates for Modicon M262 Logic/Motion Controller on the Schneider Electric website (in .zip format). |
|
2 |
Extract the .zip file to the root of the SD card. NOTE: The SD card folder \sys\cmd\ contains the download script file. |
|
3 |
Remove power from the controller. |
|
4 |
Insert the SD card into the controller. |
|
5 |
Restore power to the controller. NOTE: The SD LED (green) is flashing during the operation. |
|
6 |
Wait until the end of the download: oIf the SD LED (green) is ON, the download ended successfully. oIf the SD LED (yellow) is ON, an error is detected. A script.log file is created in the SD card \sys\cmd\ folder. |
|
7 |
Remove the SD card from the controller. Result: If the download ended successfully, the controller restarts automatically with new firmware. The restart is longer than usual. |
