Flags
There are no flags affected by these instructions.
3-31-7 CONVERT ADDRESS FROM CV: FRMCV(284)
Purpose
Converts a CV-series PLC memory address to its corresponding CS/CJ-
series PLC memory address. FRMCV(284) can be useful when converting
CV-series programs that use PLC memory addresses so that they are com-
patible with CS/CJ-series PLCs.
This instruction is supported by the CS1-H, CJ1-H, CJ1M, and CS1D CPU
Units only.

Description
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.
CCL
CCL(283) is used alone to clear the
Condition Flags after execution of
instruction A so that those results do not
affect instruction B and later instructions.
