IEC_BACNET_STACK_IP_DATALINK (STRUCT)¶

TYPE IEC_BACNET_STACK_IP_DATALINK : STRUCT

This structure defines the BACnet IP datalink type.

This structure is used for configuration of the IP datalink layer.

InOut:

Name	Type	Comment
pszDeviceName	POINTER TO IEC_BACNET_BYTE	Name (IP address) of the adapter to use.
udpPortNumber	IEC_BACNET_WORD	The udp port.
bDisableIpRouting	IEC_BACNET_BOOLEAN	The IP stack will be configured to disable IP routing for the opened socket. If set there will be no IP standard gateway and no IP routes to anything available.
bBindOnAnyAddress	IEC_BACNET_BOOLEAN	The opened socket will be bound to the ANY address if this is set. In case that more than ONE IP datalink is configured this will not work.
bBbmdActive	IEC_BACNET_BOOLEAN	The datalink is configured to act as an bbmd device.
bForeignDeviceActive	IEC_BACNET_BOOLEAN	The datalink is configured to act as an foreign device.
registrationIntervall	IEC_BACNET_WORD	The intervall for FD reregistration.
pszForeignAddress	POINTER TO IEC_BACNET_BYTE	Address of the foreign BBMD device to which we should register.
bUsesTwoHopDistribution	IEC_BACNET_BOOLEAN	The distribution will be done using a Two-Hop distribution mask (255.255.255.255) if this is set to true. The entries in the BDT are not changed but the distribution mask will be ignored in case of distribution to BBMD’s in the BDT if this is set to true.
bAllowsForeignRegs	IEC_BACNET_BOOLEAN	If set foreign devices may register with this BBMD service implementation.
bAllowBdtWrites	IEC_BACNET_BOOLEAN	If set the BDT will be writable using BVLC messages.
nBbmdDnsCancheRefreshInterval	IEC_BACNET_UINT	Time in seconds after the DNS cache is cleared and hostnames get resolved again.
pszBbmdNatRouterAddress	POINTER TO IEC_BACNET_BYTE	The external visible address for this BBMD if a NAT router is active.
bbmdList	ARRAY [0..(TARGET_SUPPORTS_IP_DATALINK_WITH_BBMD - 1)] OF IEC_BACNET_IP_BBMD_ENTRY	The array of BBMD entries. Entries which are unused shall have an IP entry with all elements set to 0 here.
