Incompatible control builder version
We used to have PM851 now we replaced to redundant PM861 controller . I can't go online with the PM861 CPU, due to version error. (We use 800xA, control builder m professional 18.104.22.168)
As in the attachment, I get an error "Its not possible to go to online mode. Incompatible Control Builder version."
As I can see from Tools--> Maintanence--> Remote Systems, CPU has 22.214.171.124 firmware as I have 126.96.36.199. And I can't downgrade CPU firmware (don't know if it is possible) due to "Communication error during data transfer". Is it possible to downgrade firmware??
I have an 800xA update but that won't work either because of incompatible 800xA version.
Where can I get appropriate 800xA update? Or is there another way around without update?
I can go online with compact control builder which is version 5.1.1 but I cant open my project since it has 5.10 hw library.
