Converting a CS/CJ-series Program with Indirect Index Register
Addressing
1. In this TOCV(285) example, an Index Register is specified in S. The CS/
CJ-series PLC memory address in that Index Register is converted to its
CV-series equivalent.
2. The CV-series PLC memory address is transferred to the specified data
area address.
3. Use the CV-series PLC memory address in the CV-series program.
