Use the following equation to calculate the effect of instance execution on the
cycle time 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.
Effect of Instance Execution on Cycle Time
= Startup time (A)
+ I/O parameter transfer processing time (B)
+ Execution time of instructions in function block definition (C)
The following table shows the length of time for A, B, and C.
