Scope	Name	Type	Comment
Return	BACnetSetObjectIdNameBindingsCacheOptions	IEC_BACNET_STATUS
Input	refreshIhaveCache	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-Has requests again. The lowest value accepted here is 10 and the default is 500 seconds.
	whoHasInterval	IEC_BACNET_UNSIGNED	Specifies the interval in which periodically Who-Has requests are sent as long as they have not been answered and thus it is also the timeout in which an answer is expected. The lowest value accepted here is 1 and the default is 5 seconds.
	whoHasRetries	IEC_BACNET_UNSIGNED	Specifies the number of retries made before dynamic resolution will stop until next refresh interval has expired. The lowest value accepted is 1 and the default is 5.
	whoHasMaxPending	IEC_BACNET_UNSIGNED	Specifies the maximum number of requests with outstanding replies which might be sent out into the network. The lowest value accepted here is 1 and the default is 20.
	bPrefillCache	IEC_BACNET_BOOLEAN	If set to True all received I-Have requests from the network are collected even if no dynamic object identifier resolution is requested for that object name.
	bAllowUnicastIhaves	IEC_BACNET_BOOLEAN	If set to True all received Who-Has requests are answered with unicast I have’s sent to the source address over which they have been received. True is the default setting for this option.
	bAllowBroadcastIhaves	IEC_BACNET_BOOLEAN	If set to True all received Who-Has requests are answered with broadcast I have’s. False is the default setting for this option.
	bUseGlobalBcastWhoHas	IEC_BACNET_BOOLEAN	If set to True all sent WhoHas gequests will use the global broadcast address to pass over BACnet routers instead of local broadcast addresses which are not routed.
