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?
