When the execution condition is ON, FRMCV(284) executes the following
operations.
1. The CV-series PLC memory address specified in S is converted to its
equivalent CV-series data area address.
2. FRMCV(284) determines the CS/CJ-series PLC memory address that cor-
responds to the same CV-series data area address.
3. The CS/CJ-series PLC memory address is output to D. (An index register
(IR0 to IR15) must be specified for D.)
The following example shows FRMCV(284) used to convert the CV-series
PLC memory address for D00001.
