LonMaker User’s Guide 305
• If a custom master shape contains several functional blocks associated with the same device, but
not the device itself, the functional block wizard appears for the first functional block only. You
must associate the functional block with its device. The remaining functional blocks are assigned
to the same device, unless no more functional blocks of the correct type are available on the
device. To be prompted for the device to be assigned to each functional block, set Force Wizard
Prompts in the network properties: General options category.
Subsystem or Supernode Master Shapes
You can include one or more LonMaker subsystem or supernode shapes in a custom master shape.
When you create a custom LonMaker shape from a subsystem or supernode shape, the LonMaker tool
copies the information for all the devices, functional blocks, connections, routers, channels, and nested
subsystems and supernodes to the master.
If you create a custom subsystem or supernode master shape that contains one or more channels the
New Channel Definition dialog box appears.
For each channel listed, click anywhere in the Method field and then select how the channel is to be
defined when the subsystem or supernode master shape is added to your LonMaker drawing. You have
four choices:
• Prompt User. The Channel Definition dialog box will appear, enabling you to select whether
the channel represents a new or an existing channel. This is the default.
• Automatic. The LonMaker tool will define the channel based on where you drop the subsystem
shape in the LonMaker drawing. If you drop the subsystem master shape on top of an existing
channel, the channel will be created as an instance of the existing channel. If you do not drop the
subsystem master shape on top of an existing channel, the Channel Definition dialog box will
appear and you select whether the channel represents a new or an existing channel.
Only one channel can have this option selected.
• Match by Name. The LonMaker tool will attempt to match the channel with an existing channel
in the network that has the same name. If it finds a match, the channel will be created as an
instance of that existing channel. If the LonMaker tool cannot find a match, the channel will be
created as a new channel.
