Control builder "function block is not called"
I have received a project from a customer that needs to make some changes in the logic. They have used som custom libraries in the project and have provided me with some .lbr files and folders containing function blocks, however when i run the "check" of the programs i get several warnings:
"The function block xxxx is not called. : Row x, Column x"
Does this indicate that i am missing a library? or is it just information to tell me that function block is declared, but not used program?

This means that the function block with this name exists in the function blocks list but not used in the application = only occupy memory of the CPU.
There is no any problem for functionality of the program.
If you double click on the warning message, CB automatically open list of function blocks, where the block is announced. Then you can simply delete this name (DEL button on the name of the block) - the warning message will dissapear
