Converts a CS/CJ-series PLC memory address to its corresponding CV-
series PLC memory address. TOCV(285) can be useful when converting CS/
CJ-series programs that use PLC memory addresses so that they are com-
patible with CV-series PLCs.
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.

In this case, the CV-series PLC memory address 0200
hex corresponds to CIO 0512. The CS/CJ-series PLC
memory address for CIO 0512 is 0000C200 hex, so this
value is stored in IR0.
