IEC_BACNET_STACK_DATALINK (STRUCT)¶

TYPE IEC_BACNET_STACK_DATALINK : STRUCT

This defines an BACnet datalink which is part of an network.

It is used for supporting different datalinks in the server API.

InOut:

Name	Type	Comment
`typ`	IEC_BACNET_STACK_DATALINK_TYPE	Type of the datalink used in this structure.
`portId`	IEC_BACNET_BYTE	The BACnet port ID used for BACnet router configuration.
`netNumber`	IEC_BACNET_WORD	The BACnet network number used for BACnet router configuration.
`receiveQueueSize`	IEC_BACNET_WORD	The size of the receiving queue in count of packets (if supported by the datalink).
`bDisableWhatIsNetnumNetnumIs`	IEC_BACNET_BOOLEAN	This flag controls if the new network management services what-is-network-number and network-number-is will be DISABLED for this datalink.
`nFilterMode`	IEC_BACNET_BYTE	The mode how the BACnet routing filter works and which filters configured network numbers and/or MAC addresses in table below received as source address to be routed into this datalink. Availabke modes: 0 = filter is off, 1 = list is passlist, 2 = list is blocklist. In passlist mode every match in the list will be routed and in the blocklist mode every match will be dropped and not routed.
`nRejectMode`	IEC_BACNET_BYTE	The mode how to reject the filtered packets: 0 = silently, 1 = reject with error-other, 2 = reject with busy-router, 3 = reject with invalid-address.
`nFilterEntries`	IEC_BACNET_UINT	The number of filter list entries in table below.
`pFilterList`	POINTER TO IEC_BACNET_ADDRESS	The entries in the filterlist. The network number is the main key to match. If the length entry for the MAC address is not BACNET_MAC_BROADCAST_LENGTH the MAC address is also compared.
`link`	UNION_BACNET_STACK_DATALINK	Union which covers all possible datalink type specific data structures.
