The ControlFlash™ Upgrade Kit includes:
• the operating system upgrade to be downloaded
• the ControlFlash programming tool, along with its support
drivers and on-line help
• a readme first file explaining how to upgrade the operating
system
Preparing for Upgrade
Before upgrading the controller’s operating system, you must:
• install ControlFlash software on your personal computer
• prepare the controller for updating
Install ControlFlash Software
For 1762-Lxxxxx controllers, double click the 1762-LSC-FRNxx.exe file
to install the operating system upgrade (where xx is the firmware
revision number).

Installing a new operating system deletes the user
program. After the operating system upgrade is
