Note When a double-length operand is used, add 1 to the value shown in the length
column in the following table.
10-5-34 Special Function Block Instructions (Unit Ver. 3.0 or Later Only)
Note When a double-length operand is used, add 1 to the value shown in the length
column in the following table.
10-5-35 Function Block Instance Execution Time (CPU Units with Unit
Version 3.0 or Later)
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.
The following table shows the length of time for A, B, and C.
