Charging station

The widget described is suitable for displaying and operating a charging station in the app. The various configuration options are described below. In the figure all available features of the widget are active.

The widget is transferred as a substructure in the overall structure of the SendData() method. To build the widget, various PLC attributes are used when declaring the structure.

{attribute 'iot.ReadOnly' := 'false'}
{attribute 'iot.DisplayName' := 'Name for Widget'}
{attribute 'iot.WidgetType' := 'ChargingStation'}
{attribute 'iot.ChargingStationReserveVisible' := 'true'}
{attribute 'iot.ChargingStationPhase2Visible' := 'true'}
{attribute 'iot.ChargingStationPhase3Visible' := 'true'}
stChargingStationWidgetSample : ST_ChargingStationWidgetSample;

Attribute	Data type	Description
iot.ReadOnly	BOOL	Determines whether the widget on the app side gets only read access (TRUE) or additionally also write access to the PLC (FALSE).
iot.DisplayName	STRING	The display name of the widget in the app. This will be overwritten by sDisplayName as soon as sDisplayName is not an empty string.
iot.WidgetType	STRING	Type specification for the widget, in this case: ChargingStation.
ioT.ChargingStationReserveVisible	BOOL	Specifies whether the reserve button is displayed (TRUE) or not (FALSE).
iot.ChargingStationPhase2Visible	BOOL	Specifies whether the values of the second phase are displayed (TRUE) or not (FALSE).
iot.ChargingStationPhase3Visible	BOOL	Specifies whether the values of the third phase are displayed (TRUE) or not (FALSE).
