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 CP-series PLC memory address that corre-
sponds to the same CV-series data area address.
3. The CP-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 in D0.
