When the execution condition is ON, TOCV(285) executes the following oper-
ations.
1. The CP-series PLC memory address specified in S is converted to its
equivalent CP-series data area address. (An index register (IR0 to IR15)
must be specified for S.)
2. TOCV(284) determines the CV-series PLC memory address that corre-
sponds to the same CP-series data area address.
3. The CV-series PLC memory address is output to D.
The following example shows TOCV(285) used to convert the PLC memory
address in IR1.
