FB Memory Area is exceeded, the User Memory is used for additional
function block definitions and instances.)

The number of function block definitions added to the number of action
programs, transition programs, and sub-charts in SFC programs.

The size of the source code for function block definitions in FB source
memory over the capacity of the FB source memory.
Note: The memory view function calculates User Memory usage from the
program open on the computer. To display memory usage on the actual
CPU Unit, upload the program from the CPU Unit so that the same
program is in both the project and the actual CPU Unit and then use the
memory view function.
