Why does FFB error comes while importing a master section in unity pro.
There are some FFBs (functions/function blocks) listed which are family dependent and can not used across Unity Pro. Lets say if a particular FFB meant for Modicon Quantum
is used with Modicon M340 / Premium selected in unity platform, then these FFBs appear marked in red and indicated as FFB "type error".
The complete list of family dependent FFB’s is available in unity pro help.
