Updating Firmware version of AB MicroLogix 1100B

Can some one please help me out about how to update firmware through RSLogix 500/Control Flash specifically for Allen Bradley MicroLogix 1100B 1763-LEC catalog>

When I try to update with control flash software i am not able to find the specified catalog number in the list.

Any help on this would be appreciated.

Thanks!

Did you get the firmware kit from the A-B website ?

Do any catalog numbers or controllers similar to the 1763-LEC appear in your ControlFlash selection window ?

Got the Answer. thank u!

We should be installing firmware .msi file before starting upgrade from control FLASH.
