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 unit configuration, which is stored in the unit memory (UM), can be
changed via the [Advanced] button in the "I/O map and unit configuration"
dialog or by specifying the settings in a user program. The following items
can be set:
 Analog output in PROG mode
 Offset/gain processing
 Scale conversion
 Upper and lower limit clipping
