REQ BOOL 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.
BASE USINT
Base Location Number Area
-The base No. on which D/A conversion module is mounted 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

Input Data Type Specification Area
-Input digital data type for each channel is specified in this area.
-Setting range: 0 ~ 4000
DONE BOOL Function Block Execution Complete Area
- When function block has been completed with no error, 1 is written and until next execution, 1 is
continuing. When error occurs, 0 is written and operation come to stop.

STAT USINT Error Code Display Area
- When error occurs during function block processing, the error code number is written.
- For error code, refer to section 4.4.
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.
