Analog Potentiometers

The all-in-one 10- and 16-I/O type CPU modules and every slim type CPU module have one analog potentiometer. Only
the 24-I/O type CPU module has two analog potentiometers. The values (0 through 255) set with analog potentiometers 1
and 2 are stored to data registers D8057 and D8058, respectively, and updated in every scan.
The analog potentiometer can be used to change the preset value for a timer or counter.
