Firmware AC700F Update Problems
I have to update an AC 700F from Freelance V9.1 to Freelance 2013. 10 seconds after starting the firmware update in Configure I get the error message "Firmware update failed: Connection to station could not be established". The engineering station is connected to the controller via an ethernet switch and I get a stable connection. When connecting to the diagnosis port of the controller I get the message I attached to this post. I can successfully flash the old V9.1 firmware in the controller. How can I flash the controller with the new firmware?
Thanks in advance,
It is a well known problem described in Product Bulletin number 3BDD011838D0298.
Updating or downgrading of PM 783F CPU firmware directly from version 9.1 to 2013 or reverse is not supported in all cases. PM 783F of Rev. B operating in a 9.1RU1a environment and temporary correction TC09 installed, can be directly updated to version 2013. Please update the firmware in two steps.
Hope this helps,
