The ability to arbitrarily alter or adjust the settings of either an experimental setup or a process control from the display screen is an integral part of SCADA systems. The DAQFactory software provides variable control icons such as rotating knobs or moveable sliders. The knob or slider page components can be coupled to an analog output channel whose value will be proportional to the rotating position of the control knob or the linear position of the slider index marker.

With proper design, the page ...
