3. Instructions
Function
When the execution condition is ON, TOCV(285) executes the following operations.
1. The CS/CJ-series PLC memory address specified in S is converted to its equivalent CS/CJ-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 corresponds to the same CS/CJ-
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 CS/CJ-series PLC memory address
for D1.

Note If there is no CV-series equivalent to the specified CS/CJ-series PLC memory address, an error will occur,
the Error Flag will be turned ON, and the address will not be converted.
