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 list when programs are written with IL(Instruction List) language. If programs are written with LD(Ladder diagram),
the following differences occur.
(1) 16 byte 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
µ
sec will be added.
