BACnetSendNetworkManagementMessage (FUN)

FUNCTION BACnetSendNetworkManagementMessage : IEC_BACNET_STATUS

Gives the user application the ability TO send network management messages.

The purpose of the BACnet network layer is to provide the means by which messages can be relayed from one BACnet network to another, regardless of the BACnet data link technology in use on that network. Whereas the data link layer provides the capability to address messages to a single device or broadcast them to all devices on the local network, the network layer allows messages to be directed to a single remote device, broadcast on a remote network, or broadcast globally to all devices on all networks. A BACnet Device is uniquely located by a network number and a MAC address.

For detailed descritions of usage of this function look under |BACNET_NETWORK_MANAGEMENT_MESSAGE| and consult chapter 6 “THE NETWORK LAYER” from ANSI/ASHRAE Standard 135-2010.
