14.3.4 Built-in variable analog potentiometer function
The main unit has two built-in variable analog potentiometers (shown in the figure below).
The current value increases from 0 to 255 when a variable analog potentiometer is turned clockwise.
The current value of each variable analog potentiometer is stored in special data registers shown below.
1. Use example 1 of variable analog potentiometer
The current value of VR1 is used as the set value of a timer.
2. Use example 2 of variable analog potentiometer
The current value of VR2 multiplied by "10" is used as the set value of a timer.
Volume Data register to store current value
VR1 : variable analog potentiometer1 D8030 (Integer from 0 to 255)
VR2 : variable analog potentiometer2 D8031 (Integer from 0 to 255)

T0
The current value of VR1 is used as the set value of the timer T0.
The setting range in this example using T0 (100ms timer) is from 0 to
25.5 sec.
D0 The current value of VR2 multiplied by "10" is used as the
set value of the timer T1.
The setting range in this example using T1 (100ms timer)
is from 0 to 255 sec.
