Can I downgradge firmware AC800F controller and IO?
Voted best answer
Hi,
Understood from question text, that you have AC 800F(PM803) + S800 i/o(gray color) that you want to use with older Freelance version V8.2. then YES so far I know you can use it. I will double confirm and will update that via comment. The controller firmware can be upgraded/downgraded via configure tool as replied in first answer.
with reference to your conversations in previous answers note that AC 800F remains in white color. but as replied gray color IO modules can be used with that in all versions.
But I suggest why not to go for Freelance new version 2013 or coming soon 2015 ?
There you get flexibility of using all gray color hardware (i.e AC 900F/700F and S700 gray color hw. etc.) plus modbus tcp protocol and several other new features.
Hope that helps...

Daer quangngoc,
Sorry to bring bad news, but what You say is impossible. ABB does not and will not sell gray AC 800F Controllers. If You bought a new PM803F it will be white, just like old ones were.
On the other hand gray hardware has exactly the same functionality as old, white one.
Best Regards,
Mike
