6.1 Basic Operation
6.1.1 Writing Analog Output Data
■
Basic operation of analog output
(1) Writing digital data
A user program is used to write digital data to the variable that corresponds to the analog
output unit channel "Ch*_ OutputValue".
The converted analog signal varies with the setting of the range.
(2) Analog conversion processing
Data written to the unit is converted to an analog signal in sequence automatically.
(3) Output to analog-driven equipment
Converted analog signal are output to inverters or other analog-driven equipment.
■
Sample program
In the following program, analog output data of ch0 "1000" of the analog output unit is written.
Declaration section
PROGRAM PRG_DAO1
VAR
iCh0_OutputValue: INT;
END_VAR
Implementation section
iCh0_OutputValue := 10000;
(Note 1)
Separately link corresponding channels in "Analog_4OUT I/O Mapping".
