Function Block Instance Execution Time; Version 3.0 Or Later) - Omron SYSMAC CS Series Operation Manual

Instruction Execution Times and Number of Steps
10-5-34 Function Block Instance Execution Time (CPU Units with Unit

Version 3.0 or Later)

Add the following value (n) to the program capacity (unit: words) of the previ-
ous PLCs for each instruction to obtain the program capacity (unit: steps) of
the CS-series PLCs.
CS-series steps = "a" (words) of previous PLC + n

For example, if OUT is used with an address of CIO 000000 to CIO 25515, the
program capacity of a C200HX/HG/HE PLC would be 2 words per instruction
and that of the CS-series PLC would be 1 (2 – 1) step per instruction.
For example, if !MOV is used (MOVE instruction with immediate refreshing),
the program capacity of a CV-series PLC would be 4 words per instruction
and that of the CS-series PLC would be 7 (4 + 3) steps.
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)
