The function block definition that has been created can be saved indepen-
dently as a function block library file (*.cxf) to enable reusing it in other
projects.
Note (1) Before saving to file, or reusing in another project, compile the function
block definition and perform a program check.
(2) When function blocks are being nested, the function block definition of the
called (nested) function blocks are included and saved in the function
block library file.
