SMB28 to SMB29: Analog potentiometer
Special memory bytes 28 and 29 contain values corresponding to analog potentiometer 0 and 1
axes position. The analog potentiometer is located in front of the CPU behind the access gate.
Use a screwdriver to adjust the potentiometer (increasing clockwise or decreasing
counterclockwise). This type of read-only value can be used by a program to perform various
functions, such as updating the current value for a timer or counter, inputting or changing a
preset value, or setting limits. It also has a rated range of 0 to 255, and reliable repeats of ±2
counts. Detailed description is shown in the following table:
