# WriteValue
This function transmits the KNX telegram including the newvalue in range 0 ÷ 65535 to the group address defined in the driver property. This function returns True if the function success, else it returns False. A function GetLastError returns the error number that occurred while executing the command. The errors that can happen: [10000](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10000), [10002](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10002), [10003](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10003), [10004](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10004), [10005](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10004).
#### Syntax
```visualbasic
Function WriteValue (
newvalue As Long,
Optional highpriority As Boolean := False)
As Boolean
```
#### Parameters
newvalue
Long It is the new value sent to the KNX bus in range 0 ÷ 65535.
highpriority
Boolean Optional, defaults to False. If it is False, then the command is applied with standard priority on the KNX bus. If it is True, then the command is applied with a high priority on the KNX bus.
#### Return value
Boolean This function returns True on success or False if an error occurs. A function GetLastError returns the error number.
# WriteTime
This function transmits the KNX telegram including data converted from parameter newtime to the group address defined in the driver property. Programmer friendly parameter newtime is used in this function. This format is suitable for DPT Dimension 7.002 to 7.007, where the time scale is defined. This function returns True if the function success, else it returns False. A function GetLastError returns the error number that occurred while executing the command. The errors that can happen: [10000](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10000), [10002](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10002), [10003](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10003), [10004](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10004), [10005](/wiki/spaces/CVCHELP/pages/510525445/Command+errors#10004).
#### Syntax
```visualbasic
Function WriteTime(
newtime As Time,
Optional highpriority As Boolean := False)
As Boolean
```
#### Parameters
newtime
Time It is the new value sent to the KNX bus. Range depends on selected DPT Dimension.
highpriority
Boolean Optional, defaults to False. If it is False, then the command is applied with standard priority on the KNX bus. If it is True, then the command is applied with a high priority on the KNX bus.
#### Return value
Boolean This function returns True on success or False if an error occurs. A function GetLastError returns the error number.
# GetValue
This function returns the last value of the group object with the given address received from the KNX bus in range 0 ÷ 65535.
#### Syntax
```visualbasic
Function GetValue() As Long
```
#### Return value
Long It is the last received value of the group object. Value is in the range 0 ÷ 65535.
# GetTime
This function returns the last value of the group object with the given address received from the KNX bus in Time format. This function is suitable for DPT Dimension 7.002 to 7.007, where the time scale is defined. In other DPT Dimensions it returns (0:0.0).
#### Syntax
```visualbasic
Function GetTime() As Time
```
#### Return value
Time It is the last received value of the group object. Range depends on selected DPT Dimension.
# OnUpdate
This event is raised when the KNX telegram with the appropriate group address is received. It returns all possible formats of data received from the KNX telegram.
#### Syntax
```visualbasic
Event OnUpdate As Process(
newvalue As Long,
newtime As Time)
```
#### Parameters
newvalue
Long It is the new value received from the KNX bus in the range 0 ÷ 65535.
newtime
Time It is the new value received from the KNX bus in time format. Range depends on selected DPT Dimension. This function is suitable for DPT Dimension 7.002 to 7.007, where the time scale is defined. In other DPT Dimensions, it is set to (0:0.0).
