BACnet mapping definitions

Location: <WorkspaceDirectory>\DataFiles\xio.BACnet.MappingDefinitions.dat

The BACnet driver also implements the BACnet Server interface. This definition file is used to configure the mapping of Server Items to BACnet objects. Each valid configuration line represents one mapping and thus creates one BACnet object within the NETx Server. The structure of the BACnet mapping definition file is as follows:

Each line – except comment lines that start with ' – defines a single BACnet mapping and thus one create BACnet object.
