14.3.3 Program modification function

The sequence program can be transferred while the PLC is running or in the stopped state as shown below.
Batch writing of file registers (D) and extension file registers (ER)
Writing of program to PLC
Writing of parameters to PLC
Writing of comments to PLC
*1. Since the writing function is used during running, the programming tool must support the write during RUN
function, such as GX Works2 or GX Developer.

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.
Volume
VR1 : variable analog potentiometer1
VR2 : variable analog potentiometer2
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.

D8031 (Integer from 0 to 255)
D8030 The current value of VR1 is used as the set value of the timer T0.
T0
The setting range in this example using T0 (100ms timer) is from 0 to
25.5 sec.

14.3 Operation and Test [Power ON and PLC Running]
The value of D8031 is multiplied by "10", and stored in
D0(D1).
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.
