Sample for calculate the memory in using:
When the FBD program contains 2 AND, 1 OR (Logic Block), 2 Timers Mode 1,
1 Counter Mode 7, RTC comparator Mode 1(Function Block), the total Diagram
Blocks used are 2+1+2+1+1=7, and the remained is 99-7=92. The timer used is
2+2=4, and the remained is 15-4=11. The counter used is 1, and the remained is
15-1=14. The RTC comparator used is 1, and the remained is 15-1=14. The analog
comparator is unused, so the usable are 15.
