Attribute | Data type | Description |
---|---|---|
iot.ReadOnly | BOOL | Determines whether the widget on the app side gets only read access (TRUE) or also additional 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: AC. |
iot.ACValueRequestVisible | BOOL | Determines whether the target value is displayed behind the current temperature value (TRUE) or not (FALSE). |
iot.ACSliderVisible | BOOL | Determines whether the slider is displayed (TRUE) or not (FALSE). |
iot.ACModeVisible | BOOL | Determines whether the mode is displayed (TRUE) or not (FALSE). |
iot.ACModeChangeable | BOOL | Determines whether the mode is adjustable (TRUE) or not (FALSE). |
iot.ACModeStrengthVisible | BOOL | Determines whether the mode for the strength is displayed (TRUE) or not (FALSE). |
iot.ACModeStrengthChangeable | BOOL | Determines whether the mode for the strength is adjustable (TRUE) or not (FALSE). |
iot.ACModeLamellaVisible | BOOL | Determines whether the mode for the slats is displayed (TRUE) or not (FALSE). |
iot.ACModeLamellaChangeable | BOOL | Determines whether the mode for the slats is adjustable (TRUE) or not (FALSE). |
iot.DecimalPrecision | INT | Sets the number of decimal places. This setting overwrites the setting at the variable nTemperature. |

Attribute | Data type | Description | Display in widget |
---|---|---|---|
sDisplayName | STRING | Determines the display name of the widget and overwrites the PLC attribute 'iot.DisplayName'. | Display text of the widget. |
nAcMode | INT | Determines the mode of the AC widget. | Icon top right. |
iot.Unit | STRING | Unit of the temperature value. | Unit behind both numerical values. |
iot.MinValue | INT | Lower limit of the temperature range. | On the left side under the slider. |
iot.MaxValue | INT | Upper limit of the temperature range. | On the right side under the slider. |
iot.DecimalPrecision | INT | Number of decimal places for the temperature values. Overwritten by the DecimalPrecision on the widget and applies to both temperature values. | For both temperature values. |
nTemperature | LREAL | Current temperature value. | The number on the left side of the arrow. |
nTemperatureRequest | LREAL | Requested temperature value, possible via the slider in steps of 0.1. | The temperature requested via the slider is then displayed on the right side of the arrow. |
sMode | STRING | Mode of the air conditioning system. | The currently displayed mode (left). |
aModes | ARRAY [0..n] OF STRING | Array of the different general modes that can be set by the user. | By pressing on the current mode (left), the adjustable modes can be displayed. |
sMode_Strength | STRING | Mode of the stage of air conditioning system. | The currently displayed mode (centered). |
aModes_Strength | ARRAY [0..n] OF STRING | Array of the different step modes adjustable by the user. | By pressing on the current mode (centered), the adjustable modes can be displayed. |
sMode_Lamella | STRING | Mode of the louvers of the air conditioning system. | The currently displayed mode (right). |
aModes_Lamella | ARRAY [0..n] OF STRING | Array of the different louver modes adjustable by the user. | By pressing on the current mode (right), the adjustable modes can be displayed. |
