9 Creating SNVTs
For more information about SNVTs and controller objects, see
Section 10.1, “Defining SNVTs and Controller Objects”, on page 81.
9.1 Adding a Controller Object and a SNVT
In the following example, you create a SNVT in the Xenta 913 that
propagates a value, in the example Tot_real_power, from the energy
meter on the Modbus interface.
This requires that you add a controller object, this is like a container for
SNVTs, and a network variable (SNVT).
After you have added the SNVTs to XBuilder and generated the project,
a new .xif file for the Xenta 913 is generated. The new .xif file is used
by the LNS database to make the new SNVTs in the Xenta 913 avail-
able for binding in LonMaker.
