Updating the Controller Firmware by Controller Assistant

Before Updating Firmware

Performing a firmware update deletes the application program in the device, including the configuration files, the user management, the user rights, the certificates and the Boot Application in non-volatile memory.

NOTICE
	LOSS OF APPLICATION DATA Perform a backup of the application program to the hard disk of the PC before attempting a firmware update. Restore 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 Do not interrupt the transfer of the application program or a firmware change once the transfer has begun. Re-initiate the transfer if the transfer is interrupted for any reason. Do 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.
