334 Appendix A - Setting LonMaker Default Options
Naming Options
The Naming category contains the following options. The changes you make in the Naming options
category are applied to the current network on your computer.
Naming Options Controls how the LonMaker tool constructs a unique name for new
LonMaker shapes. If there is a naming conflict, the LonMaker tool
will append to a new LonMaker shape name a space, dash, or other
selected separator character followed by an instance ID. The instance
ID starts at 1 and is incremented by one each time a new shape of a
given type (device, router, functional block, and so on) with an
identical name of an existing shape is added to your LonMaker
drawing.
For example, the default name of the first generic device shape added
to your LonMaker drawing is Device. The second generic device
shape is Device 1, but you can change this to Device1, Device-1, or
Device-001 based on the naming options you set.
