详细描述

This datapoint type may only be used for encoding the combined binary output information of a multiple-channel binary actuator. It avoids the bus load that is caused by individual single bit state outputs, especially in case of simultaneous changes, such as all off .

If one or more output bits are not used or the output states are not valid, the assigned mask bits of the output shall be set to the value 0 .

This is a fixed size datapoint type with the length of 4 bytes.

QKnxCombinedInfoOnOff:: QKnxCombinedInfoOnOff ( QKnxCombinedInfoOnOff::Output output , QKnxCombinedInfoOnOff::OutputState state , QKnxCombinedInfoOnOff::OutputValidity validity )

Creates a fixed size datapoint type with the output bit output , state state , and validity validity .

QKnxCombinedInfoOnOff:: QKnxCombinedInfoOnOff (const QVector < QKnxCombinedInfoOnOff::OutputInfo > & infos )

Creates a fixed size datapoint type with the output information infos .

QKnxCombinedInfoOnOff:: QKnxCombinedInfoOnOff ()

Creates a fixed size datapoint type with the output bit set to QKnxCombinedInfoOnOff::First , output state to QKnxCombinedInfoOnOff::Off , and output validity to QKnxCombinedInfoOnOff::Invalid .

bool QKnxCombinedInfoOnOff:: setState ( QKnxCombinedInfoOnOff::Output output , QKnxCombinedInfoOnOff::OutputState state )

bool QKnxCombinedInfoOnOff:: setValidity ( QKnxCombinedInfoOnOff::Output output , QKnxCombinedInfoOnOff::OutputValidity validity )

Sets the output bit stored in the datapoint type to output and the validity to validity .

If the value is outside the allowed range, returns false and does not set the value.

另请参阅 validity ().

bool QKnxCombinedInfoOnOff:: setValue (const QVector < QKnxCombinedInfoOnOff::OutputInfo > & infos )

Sets the value stored in the datapoint type to infos .

返回 true if the value was set successfully; otherwise returns false .

bool QKnxCombinedInfoOnOff:: setValue ( QKnxCombinedInfoOnOff::Output output , QKnxCombinedInfoOnOff::OutputState state , QKnxCombinedInfoOnOff::OutputValidity validity )

Sets the output bit stored in the datapoint type to output , the output state to state , and output validity to validity .

返回 true if the value was set; otherwise returns false .

QKnxCombinedInfoOnOff::OutputState QKnxCombinedInfoOnOff:: state ( QKnxCombinedInfoOnOff::Output output ) const

Returns the state of the output bit output .
