BACnetServer (FB) ¶ FUNCTION_BLOCK PUBLIC FINAL BACnetServer IMPLEMENTS IBACnetServerInternal, CmpEventMgr.ICmpEventCallback, IBACnetEventConsumer FB representing the BACnet-Server, which is the core of any BACnet-Application. Each BACnet-Server gets assigned one BACnet-Device-Object, which is initialized together with the BACnet-Server (properties of the BACnet-Device-Object are part of the BACnet-Server-CODESYS-Device as parameters). All BACnet-Object (BACnet-Object-CODESYS-Devices) added as childs of a BACnet-Server are consequently under the corresponding BACnet-Device-Object. This BACnet-Server-FB is responsible for starting the BACnet-Server on the CODESYSControl-Component side (using CmpBACnet.BACnetServerInit), which eventually makes all BACnet-Objects under this BACnet-Server visible in the BACnet network. There are two options for starting/stopping the BACnetServer which could be configured. The first option “AutoStart=TRUE” starts the BACnetServer when the application owning the BACnetServer-FB is loaded. The second option “AutoStart=FALSE” allows programmatic start/stop of the BACnetServer, using BACnetServer.StartBACnetStack() / StopBACnetStack(). This option should be used, if object initialization data needs to be computed (not configured in the device tree), to ensure the BACnetServer is started with consistent object definitions. Apart from this the BACnet-Server-FB gives the functionality to register FBs implementing IBACnetEventConsumer for Hooks and Callbacks. Moreover some additional functionalities for specific services are provided. To get an idea how to use most important BACnet server features and services please refer to several examples provided with(in) the CODESYS BACnet package.

BACnetServer.DemoMode (PROP) ¶ PROPERTY DemoMode : BOOL Returns true, if BACnetServer is running in DemoMode (without proper license).

BACnetServer.GetAddressBindingsCount (METH) ¶ METHOD GetAddressBindingsCount : UDINT Gets the count of address bindings in the BACnet-Network. This means return the count of the list of BACnet-Devices with their addresses of the entire BACnet-Network. InOut: Scope Name Type Return GetAddressBindingsCount UDINT

BACnetServer.UpdateAddressBindings (METH) ¶ METHOD UpdateAddressBindings Deletes all existing Bindings and Sends Who-Is Broadcasts to the BACnet-Network, in order to get I-Am-Answers, which will update the Device-Address-Bindings-List receivable by GetAddressBinding and GetAddressBindingCount. Note There should be a reaction time for the I-Am-Answers to be transmitted, so don’t call this function to often in to short intervalls. Moreover on every call the existing Bindings-List gets deleted, so that it has to be rebuild, which might take a longer time.

DeviceAddressBindings ¶ Functionalities to get and update the device address bindings within a BACnet server. GetAddressBinding (Method) GetAddressBindingsCount (Method) UpdateAddressBindings (Method)

BACnetServer.GetAddressBinding (METH) ¶ METHOD GetAddressBinding Returns the address binding with index nIndex in the List of BACnet-Devices and their adresses in the entire BACnet-Netowrk. InOut: Scope Name Type Comment Input nIndex UDINT The 1 based index of the device in the list of address bindings. Inout binding CmpBACnet.IEC_BACNET_ADDRESS_BINDING Any empty address binding, which is filled with the Bidning at index nIndex.
