Updating the Firmware
The card supports firmware and FPGA upgrade across the ControlLogix
backplane using the Rockwell ControlFlash utility.
Install the ControlFlash software from the 56AMXN distribution CD and
run it as you would to update any other ControlLogix module. Refer to
the ControlFlash documentation and help for detailed information on
how to use ControlFlash.
A 56AMXN/A can be upgraded to 56AMXN/B functionality by simply
upgrading the firmware. No hardware changes are required.
