CJ-series Instruction Execution Times and Number of Steps

Only)
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.
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.

CJ-series Instruction Execution Times and Number of
Steps
The following table lists the execution times for all instructions that are avail-
able for CJ PLCs.
The total execution time of instructions within one whole user program is the
process time for program execution when calculating the cycle time (See
note.).
Note User programs are allocated tasks that can be executed within cyclic tasks
and interrupt tasks that satisfy interrupt conditions.
