FUNCTION BACnetReadProperty : IEC_BACNET_STATUS

Sends a ReadProperty request

InOut:

Scope	Name	Type	Comment
Return	`BACnetReadProperty`	IEC_BACNET_STATUS
Input	`pSourceAddress`	POINTER TO IEC_BACNET_ADDRESS	If the BACnet application has only one device constructed and installed, this can be NULL. In this case the MAC address of this device will be used. Otherwise this shall be the MAC address returned on device object construction.
	`pDestinationAddress`	POINTER TO IEC_BACNET_ADDRESS	This is the MAC address of the device to which the request should be sent.
	`pServiceInfo`	POINTER TO IEC_BACNET_READ_INFO	A pointer to a data structure which contains all service parameters this service provides and the application needs to process.
	`pAPDUParams`	POINTER TO IEC_BACNET_APDU_PROPERTIES	A pointer to the structure which contains a set of APDU properties to control the timing and size of transmitted frames for this request. It temporarily overwrites the global APDU settings made in the source device from which this request is sent and which parameters would control this request if this pointer is NULL.
	`pTransactionToken`	POINTER TO BACnetAsyncTransactionToken	Transaction token of the asynchronous call - see BACnetAsyncTransactionToken.
	`pContents`	POINTER TO IEC_BACNET_PROPERTY_CONTENTS	This pointer references the data structure in which any successful service execution result is stored.
	`pError`	POINTER TO IEC_BACNET_ERROR	In case of any service execution error the error result will be stored in the structure this pointer references. This parameter may be NULL if the application isn’t interested in detailed error information.
