BACnetInstnumberToDeviceAddress (FUN) ¶ FUNCTION BACnetInstnumberToDeviceAddress : IEC_BACNET_STATUS Function retrieves the BACnet MAC address for an b LOCAL device instance. This functionm is needed if the appication needs to know it’s own device address and how it needs to look if it should be reachable across BACnet networks. For e.g. the application needs to know it’s own address for an specific network because it needs to write an entry into some recipient list.

After expiration of the refresh interval all bindings are requested using Who-Is requests again. The lowest value accepted here is 10 and the default is 500 seconds. whoIsInterval 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. The lowest value accepted here is 1 and the default is 5 seconds. whoIsRetries 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. whoIsMaxPending IEC_BACNET_UNSIGNED Specifies the maximum number of requests with outstanding replies which might be sent out into the network.

True is the default setting for this option. bAllowBroadcastIams IEC_BACNET_BOOLEAN If set to True all received Who-Is requests are answered with broadcast I am’s. False is the default setting for this option. bUseGlobalBcastWhoIs 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.

BACnetSetHook (FUN) ¶ FUNCTION BACnetSetHook : IEC_BACNET_STATUS Sets / registers a service hook Registers a hook routine, which is the service application hook. The service application hook may override the default API processing of some BACnet service requests. A hook can be registered at any time. One hook procedure is registered per service. If the same service is hooked more than once (the hook is registered more than once for the same service), the new hook procedure replaces old one. A NULL procedure pointer cancels the hook. InOut: Scope Name Type Comment Return BACnetSetHook IEC_BACNET_STATUS A status indicating whether the operation worked. Input eHookType IEC_BACNET_CB_TYPE The hook type which shold be registered. pICallback CmpEventMgr.ICmpEventCallback A pointer to the hook event interface.
