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

Note Duplex CPU Systems only. These functions are not supported by Duplex CPU
Systems.
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 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 CJ-series PLC would be 7 (4 + 3) steps. (Duplex CPU Systems
only. Immediate refreshing is not supported by Duplex CPU Systems.)
