A Human-Machine Interface (HMI) system comprises a machine interface, a processing system, and a user interface. The machine interface receives operational data associated with an operation of a machine. The processing system processes the operational data associated with the operation of the machine to determine a trend in the operational data. The user interface displays a graphical representation of the trend, and receives a first user input and a second user input simultaneously on a surface of the user interface. The processing system processes the first user input and the second user input to determine a change in the trend. The user interface displays a graphical representation of the change in the trend.

Fuzzy logic programming is provided for machine and process controllers. New input and output instructions are devised for ladder diagram programming, as well as methods of downloading fuzzy logic instructions from a programming terminal to a programmable controller processor and methods for executing such instructions in the programmable controller processor.
