Echelon DM-21 Device Manager - Manual (Page 67)

1. Download the example photocopier network from
www.echelon.com/products/dm . This network is not intended to be operable,
however, it is sufficient to illustrate the use of the Loading Wizard when
designing a network containing multiple subsystems.
2. Use the LonMaker for Windows Integration Tool to restore the archived
network. Browse the network and observe the subsystem hierarchy.
3. Using the Device Manager Loading Wizard, include all four subsystems in
the managed device list as shown in figure 5.13.
Figure 5.13 – Subsystem Selection
Note which PIN is associated with each subsystem. When the Device
Manager is installed, set the correct 4-bit subsystem selection input on the
Device Manager’s input pins. Reorder the subsystems using the arrow
buttons if desired.
4. Continue compressing and loading the Device Manager as shown in steps 8 to
18 in Example 1, earlier in this chapter.
• Examples 1 and 2 use single subsystems so the 4-bit subsystem selection
input to the Device Manager was not necessary at runtime for subsystem
selection. Example 3 has 4 subsystems, each containing a Device Manager
and all the nodes required for configuration of the photocopier. Depending on
the desired photocopier configuration, a different subsystem is selected using
the 4-bit subsystem selection input.
