CJ-series Instruction Execution Times and Number of Steps
Section 4-2
4-2-33 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 CJ-
series PLCs.
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 CJ-series PLCs.
For example, if OUT is used with an address of CIO 000000 to CIO 25515, the
program capacity of the previous PLC would be 2 words per instruction and
that of the CJ-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 CJ-series PLC would be 7 (4 + 3) steps.
CJ-series steps = “a” (words) of previous PLC + n
