BACnetWritePropertyInstanceByHandle (FUN)ΒΆ
FUNCTION BACnetWritePropertyInstanceByHandle : IEC_BACNET_STATUS
Same function as BACnetWritePropertyInstance but uses handle to object instead of an device instance number and object idenfier.
- InOut:
- Scope - Name - Type - Comment - Return - BACnetWritePropertyInstanceByHandle- Input - handleToObject- A valid handle to the object retrieved by a call to BACnetGetObjectHandle. - ePropertyID- The Property identifier of the local property. - nIndex- The index of an array item. If the Property is not an array, the index value BACNET_VOID_INDEX (-1) should be used. If the Property is an array, the index value BACNET_ENTIRE_ARRAY (-1) can be used to write the entire array. If the Property is an array, the index value BACNET_ARRAY_COUNT (0) can be used to resize the array provided that this array can be variable size. The indices of BACnet arrays start counting at 1. - priority- The priority level for the Write-Property request, if the Property is a commandable Property (such as the present-value property of Output and Value Objects). If the Property is not commandable, the priority level BACNET_VOID_PRI should be used. If the Property is commandable, a priority level from 1 to 16 or BACNET_DEFAULT_PRI (16) can be used. The value is written into the Priority-Array Property of the object, and the highest priority value in that array is used as the value for the commandable property. - pValue- POINTER TO IEC_BACNET_PROPERTY_CONTENTS - A pointer to a Property Contents containing the value of the Property. The Property Contents tag attribute must indicate the data type of the Property. - pError- POINTER TO IEC_BACNET_ERROR - A pointer to store the returned BACnet error code.
