4.2.11 Built-in analog variable potentiometers [D8030, D8031, D8013]

• Program for built-in analog variable potentiometers
Program values for built-in analog variable potentiometers are stored in the following special data registers
as numeric data within the range from 0 to 255 in accordance with the scale position.
Values received as numeric values can be specified as the indirectly specified value for a timer to provide
variable potentiometer type analog timers.
