FUNCTION BACnetGetDeviceAddressBindingsCacheOptions : IEC_BACNET_STATUS

Configures timing an retry parameters for the ‘dynamic’ address binding procedure.

This function reads the timing and retry parameters for the ‘dynamic’ address binding procedure as defined in the BACnet standard.

Return: IEC_BACNET_STATUS

InOut:

Scope	Name	Type	Comment
Return	`BACnetGetDeviceAddressBindingsCacheOptions`	IEC_BACNET_STATUS
Input	`pRefreshIamCache`	POINTER TO IEC_BACNET_UNSIGNED	Specifies the refresh time in seconds after all listed dynamic bindings get refreshed. After expiration of the refresh interval all bindings are requested using Who-Is requests again.
	`pWhoIsInterval`	POINTER TO IEC_BACNET_UNSIGNED	Specifies the interval in which periodically Who-Is requests are sent as long as they have not been answered and thus it is also the timeout in which an answer is expected.
	`pWhoIsRetries`	POINTER TO IEC_BACNET_UNSIGNED	Specifies the number of retries made before dynamic resolution will stop until next refresh interval has expired.
	`pWhoIsMaxPending`	POINTER TO IEC_BACNET_UNSIGNED	Specifies the maximum number of requests with outstanding replies which might be sent out into the network.
	`pbPrefillCache`	POINTER TO IEC_BACNET_BOOLEAN	If set to True all received I-Am requests from the network are collected even if no dynamic address resolution is requested for that device.
	`pbAllowUnicastIams`	POINTER TO IEC_BACNET_BOOLEAN	If set to True all received Who-Is requests are answered with unicast I am’s sent to the source address over which they have been received.
	`pbAllowBroadcastIams`	POINTER TO IEC_BACNET_BOOLEAN	If set to True all received Who-Is requests are answered with broadcast I am’s.
	`pbUseGlobalBcastWhoIs`	POINTER TO IEC_BACNET_BOOLEAN	If set to True all sent WhoIs gequests will use the global broadcast address to pass over BACnet routers instead of local broadcast addresses which are not routed.
