AC 800M PM866 redundant controller fault light blinking
I have PM866 redundant controller.One is working properly but the redundant one fault light blinking.So I go through abb manual and found controller waiting for firmware update as mentioned in manual.Now i remove controller from panel and connect with PC in which abb software is installed by TK212A serial cable which is connected at COM4 in controller. Now I open serial firmware upgrade and click connect option & push INIT button to reset the controller but it's RUN led not blinking and after sometime showing not connected Timeout.So I am not sure is it hardware related problem or software related? is there otherway to update its firmware?

Remove backup battery (internal or external) and try serial upgrade again. Press & hold init until red LED starts to flash.
If serial firmware upgrade fail, ask regional ABB Support for assistance with diagnose/replacement.

Hello,
Be ensure the following while upgrading the firmware in the red controllers.
1.disconnect he RCU link cable from the CPU to which you are going to upgrade and connect the RCU link/ TB852 terminator.
2.remove the battery if any
3.remove the CN1/CN2 if you are using PPP for serial firmware upgrade.
4.open the firmware upgrade utility and press connect and press INIT button on the controller till R flashes for 3 times
then the upgrade the firmware.
