4.1 Writing of analog output data

Sample program
20
The processing of digital input data takes place in three steps:
1. Writing of digital data
A user program is needed to write the digital input values to the analog
unit into the CPU's output area (WY) on a channel-by-channel basis.
2. Digital to analog conversion
The digital input values are converted to analog output values automat-
ically and in sequence.
3. Analog signal output
Analog signals are output to inverters or other analog-driven equip-
ment.
Q Digital input value
W D/A conversion
E Analog signal
The digital input values to the analog output unit are stored by channel in
four different variables. They will be written to the CPU's memory areas
DIXWY0, DIXWY2, DIXWY4, and DIXWY6.
