Model Code
Initial value: K2
Numeric data type: Decimal (K)
1. Description of setting
When the 4DA-ADP is connected, model code "2" is stored in the corresponding special data register.
The following table shows the special data registers that store the model code:
• FX
3U
, FX
3UC
 Series PLC
• FX
3G 
Series PLC
Use the special data registers above to check whether 4DA-ADP is connected or not.

Basic Program Example
Create the following basic program example to output D/A converted analog data.
• For  FX
3G
, FX
3U
, FX
3UC
 Series PLC
The following program will set channel 1 of the 3rd
*1
 adapter to the voltage output mode and channel 2 to
current output mode, and will set digital data in D100 and D101 for D/A conversion.
Using the indicator or the sequence program, input the digital data to be subject to D/A conversion (to be
output as analog data) in D100 and D101.
