4. From the Device Manager Shapes stencil drag and attach a Device Manager
device to the default channel that the LonMaker tool provides upon start up.
5. From the LonPoint Shapes stencil drag and drop a Digital Input functional
block to the LonMaker network drawing. When prompted, be sure to
specify the DI and not the DM as the source of the input.
6. From the LonPoint Shapes stencil drag and drop a Digital Output functional
block to the LonMaker drawing. When prompted, select the output from the
only device that has outputs – the DO module.
7. Connect the input to the output. The drawing should look something like
Figure 5.1.
Figure 5.1 – LonMaker Network for Example 1
All the devices in the drawing exist in subsystem 1. When the loading wizard
compresses the database, only subsystem 1 will be selectable; no other
subsystems are specified in the drawing.
The Device Manager is part of the network and therefore must appear as a
device in subsystem 1 since the devices it will manage are in subsystem 1.
Although the Network Service Device (NSD) appears in the subsystem, it will
be ignored by the Device Manager.
All four devices in the network have different program IDs so it was not
necessary to define the location string for any of the devices.
