Remark
Note 1: Array number of data type means the whole number of channels and channel number.
Array number of G3F-DA3V/G3F-DA3I/G4F-DA3V/G4F-DA3I is 8 and array number of G4F-DA2V/G4F-DA2I
/G6F-DA2V/G6F-DA2I is 4.

Function Block Execution Request Area
-The execution of function block initialization is requested in this area.
-If the status connected with this area is satisfied on the program execution and 0 is changed to 1,
function block for the module is executed.
USINT
Base Location Number Area
-The base No. on which D/A conversion module is mount e d is written on this area.
-Setting range : G3F-DA3V,G3F-DA3I,G4F -DA3V,G4F-DA3I,G4F-DA2V,G4F-DA2I : 0 to 3
G6F-DA2V,G6F-DA2I : 0
USINT
Slot Location Number Area
