CJ-series Instruction Execution Times and Number of Steps
Section 4-2
4-2-34 Special Function Block Instructions (CPU Unit Ver. 3.0 or Later
Only)
4-2-35 Number of Function Block Program Steps (CPU Units with Unit
Version 3.0 or Later)
Use the following equation to calculate the number of program steps when
function block definitions have been created and the instances copied into the
user program using CS/CJ-series CPU Units with unit version 3.0 or later.
Note
The number of instruction steps in the function block definition (p) will not be
diminished in subsequence instances when the same function block definition
is copied to multiple locations (i.e., for multiple instances). Therefore, in the
above equation, the number of instances is not multiplied by the number of
instruction steps in the function block definition (p).
