AC900F Firmware Update Error
I have a AC900F and a Freelance 2019.
In Freelance Engineering I encountered a DMS version error in the controller so what i want to do now is to update the firmware of the AC900.
On the Freelance Settings, i encountered error on the Firmware Update when i click Load Button a pop-up appears "Connection to Controller could not establish"
I can ping the Controller and it can be detected in Freelance Engineering.
WHAT TO DO?
You can connect DIAG port to the TERMINAL application and when trying to upgrade firmware should see something like "Invalid BootCode Version...current version 2.15, expected:2.17" if so you should upgrade at first to Freelance 2016 and then after to Freelance 2019
That might be because of the default firmware version that comes already in the controllers is older than 2016 o 2013 so the boot could not load or start loading the new 2019 firmware.
