Appendix D Use ControlFLASH to Upgrade Your Operating System
Alternatively, you can enable SNMP with the LCD display. For more
information, see Configure Ethernet Protocol Setup on page 105
2. Ensure that you complete the IP configuration for the OS firmware
update. Note the assigned IP address of the controller.
If the IP address is not configured, you can still perform the IP
configuration with Static, BOOTP or DHCP settings. Once the IP
configuration is done, it is used throughout the firmware update
process.
If the IP configuration has been done, the IP address may be read from
the processor when online with RSLogix 500/RSLogix Micro. In the
Channel Configuration dialog box, select the Chan. 1 – System tab or use
the LCD.
3. Set the controller to Program mode before you start the firmware update
(access the Mode Switch from the LCD).
See Mode Switch
on page 94 for information about controller modes and how
to use the Mode Switch.
See View Ethernet Status
on page 99 to find how to browse for the controller’s
IP address.
Use ControlFLASH for
Firmware Update
1. Launch the ControlFLASH application under Programs>Flash
Programming Tools.
If the Ethernet connection (IP configuration) has not been established,
attach an Ethernet cable to the controller from your computer (or a hub),
and ensure that the Ethernet connection is intact throughout the
upgrade process.
IMPORTANT The user program is cleared as part of the operating system
upgrade process. You must restore your program after successfully
loading the operating system upgrade. The Ethernet communication
configuration parameters are retained after a successful firmware
update.
IMPORTANT A power cycle is needed in order for the changes in the Channel
Configuration page to be applied.
ATTENTION: Do not interrupt the update procedure once you have begun to
download the firmware. If the update procedure is interrupted, the controller is in
a Missing or Corrupt OS state on the next power-up.
To recover the controller from a missing/corrupt OS state, see Missing or Corrupt
OS state on page 172.
IMPORTANT If you are connecting to the controller through a hub, you can use a
standard Ethernet patch cable.
If you are connecting to the controller directly from your computer, you
must use an Ethernet crossover cable.
