Green means running, amber means attention, red means stopped, blue is a call for assistance and white is a changeover. The component can be driven by a state word such as running, starved or fault, which the stateMap property translates into segments that are on, off or flashing, or segment by segment when the application mirrors the outputs of the physical tower. The horn is switched on by the application, and pressing it raises the muteRequest event.
Press the horn on the case packer. The component raises the muteRequest event and the application mutes the horn.
A tower takes the five standard colours, red, amber, green, blue and white, and further segments in any CSS colour. The legend shows the name and state of each segment; the same text is used as the accessible name. The orientation property lays the tower horizontally for a header strip.
A plant with a different lighting convention replaces the map. In this example starved lights amber and blue together, and a sixth, plant-specific segment shows a quality hold.
