2.4 Analog Potentiometer
2.4.1 Overview of Analog Potentiometer
The FP
Σ
is equipped with two analog potentiometers as a standard feature. Turning the potentiometers
changes the values of the special data registers DT90040 and DT90041 within a range of K0 to K1000.
Using this function makes it possible to change the internal set values in the PLC without using the
programming tool, so this can be used, for example, with analog clocks, to change the set value
externally by turning the potentiometer.

e Showing How to Use Analog Potentiometer
The FP
Σ
is provided with special data registers, in which the values in the registers change in response
to the analog potentiometers being moved. If the values of these registers are sent to the clock setting
value area, a clock can be created that allows the time to be set using the potentiometer.
Example: Writing of the clock setting value
The value of the special data register (DT90040) that corresponds to the analog potentiometer V0 is sent
to the setting value area (SV0) of TMX0 to set the time for the clock.
