1) Example in which the read analog value is used as the set value of an analog
timer. (VRRD instruction)
The analog value of the variable analog potentiometer No.0 is converted into
binary 8-bit data, and the value in the range from 0 to 255 is transferred to D0.
The value of D0 is used as the set value of a timer

When a value larger than 255 is required as the set value of a timer, the read
value multiplied by a constant by the FNC22 (MUL) instruction can be set
indirectly as the timer constant.
2) Example in which the scale value is used as a rotary switch. (VRSC instruction)
Either one among auxiliary relays M0 to M10 turns ON in accordance with the
scale value in the range from 0 to 10 of the specified variable analog
potentiometer.
