CS/CJ/NSJ Series Instructions Reference Manual (W474)
4. Instruction Execution Times and Number of Steps
Example: CS1H-CPU63H
Input variables with a 1-word data type (INT): 3
Output variables with a 1-word data type (INT): 2
Total instruction processing time in function block definition section: 10 s
Execution time for 1 instance = 6.8 s + (3 + 2)
Note The execution time is increased according to the number of multiple
instances when the same function block definition has been copied
to multiple locations.
Note Guidelines on Converting Program Capacities from Previous OMRON PLCs
Guidelines are provided in the following table for converting the program
capacity (unit: words) of previous OMRON PLCs (SYSMAC C200HX/HG/HE,
CVM1, or CV-series PLCs) to the program capacity (unit: steps) of the CS-
series PLCs.
Add the following value (n) to the program capacity (unit: words) of the previ-
ous PLCs for 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 CVM1 or CV-series PLC would be 4 words per
instruction and that of the CS-series PLC would be 7 (4 + 3) steps.
Note 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.
Number of steps
= Number of instances
ber of parameters) + Number of instruction steps in the function block definition p
