• The FP-XH M8N control unit equipped with an analog potentiometer.
• When rotating the potentiometer, the value of the special data register DT90040 changes
between K0 - K4000. The set values inside the PLC can be changed without using a
programming tool, therefore, it can be used to analog timers that change the set values by
external rotary potentiometer.
