4.7 Model Code
Initial value: K2
Numeric data type: Decimal (K)
1. Description of setting
When 4DA-ADP is connected, model code "2" is stored in the special data register.
The following table shows the special data registers that store the model code:
Use the above special data registers to check whether 4DA-ADP is connected or not.
2. Example of program
4.8 Example of Basic Program
Create the basic example program to output D/A converted analog data.
The following program will set channel 1 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.
