Upgrading Your Operating System
The operating system (OS) can be upgraded through the
communication port on the controller. In order to download a new
operating system, you must have the following:
• ControlFLASH™ Upgrade Kit containing the new OS
• a Windows
®
95, Windows
®
98, Windows NT™, or
Windows
®
2000 based computer to run the download software.
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:
• Obtain the operating system upgrade from
http://www.ab.com/micrologix
or from your local Allen-Bradley
distributor
• Install the ControlFlash Software. Double click the processor
catalog number/firmware revision number to install the
operating system upgrade.
• The controller must be configured for default communications
(use communications toggle push button; DCOMM LED on) and
be in the Program mode to allow the download of a new
operating system.
IMPORTANT
Installing a new operating system deletes the
controller’s user program.
