Example 2: Converting a CV-series Program with PLC Memory
Addresses Stored directly in Index Registers
In this FRMCV(284) example, the CV-series PLC memory address is speci-
fied directly in S.
3-29-7 CONVERT ADDRESS TO CV: TOCV(285)
Purpose Converts a CS/CJ/CP-series PLC memory address to its corresponding CV-
series PLC memory address. TOCV(285) can be useful when converting CP-
series programs that use PLC memory addresses so that they are compatible
with CV-series PLCs.

• CP-series program
Equivalent program
In this case, the PLC memory address
0200 hex is stored in Index Register IR0.
In this case, the CV-series PLC memory address 0200 hex
corresponds to CIO 512. The CP-series PLC memory
address for CIO 512 is 0000C200 hex, so this value is
stored in IR0.
