Appendix 3. Function / Function Block Lists
App3-2
REMARK
1) The items marked with ‘
∗
‘ has following meaning.
∗ 1: The size of the program memory which a program occupies when it uses the function once
∗ 2: The size of the program memory which a program occupies only one time though it uses the function many times
∗ 3: of IL programs (2 input variables, 10 strings)
2) The above shows the function lists when programs are written with IL (instruction List) language.
If programs are written with LD (Ladder diagram), the following differences occur.
(1) 16 bytes will be added to the size of the PB.
(2) In non-execution, 0.4 will be added to the processing speed. In execution, 0.8 sec will be added.

REMARK
1) The items marked with ‘
∗
‘ has following meaning.
∗ 1: The size of the program memory which a program occupies when it uses the function once
∗ 2: The size of the program memory which a program occupies only one time though it uses the friction many times
∗ 3: The size of the program memory which a program occupies whenever it uses the function block once
2) The occupied memory size and processing speed of IL programs are same as LD programs.
