Abstract
The invention provides consistent settings between local and remote parameter adjustments of both local and remote HMI. A dial (4) is superimposed on a bistable display substrate (2), having an indicator (7) configured to be manually aligned with a displayed character representing a manual setting of a parameter value for controlling local equipment. A network interface (18) is connected over a communications network (17) to a remote HMI (16), configured to receive a new parameter value for controlling the local equipment (25). A controller (14) samples the current position of the indicator (7) of the dial (4), and provides a control input signal (20) to the bistable display substrate (2) to control a display of the new parameter value in the current position of the indicator (7) of the dial (4) and to provide the new parameter value to the local equipment (25).
