since the different allocation algorithms used for managed and self-installed
connections could result in duplicate resources being assigned. Managed devices
and self-installed devices must always be installed in different domains.
The NodeBuilder tool is the best tool for developing and debugging Neuron C
applications, but there are three other tools that you can use to aid debugging:
• The ISI Packet Monitor Application is a free utility included with
the ISI Developer’s Kit. You can use it to monitor and decode most
ISI messages. To start the ISI Packet Monitor Application, open
the Windows Start menu, point to Programs > Echelon
Interoperable Self-Installation, and then click ISI Monitor Packet
Application. After the Network Interface windows opens, select
your channel type and network interface, and then click Connect.
The ISI Packet Monitor window appears. ISI packets received by
the selected network interface are interpreted and listed in the
lower pane. You can highlight text in the lower pane, right-click
the highlighted text, and then click Copy on the shortcut menu to
copy the log to the Windows clipboard. You can select one of three
tabs in the upper pane to show a summary of devices reporting
DRUMs, a summary of connections reporting CSMx’s, or a
summary of ISI message statistics.
• The NodeUtil Device Utility is a free utility that is available for
download from www.echelon.com/downloads . This application
allows you to see various aspects of a device, including memory and
network variable tables, and also allows you to view and update
network variables.
• The LonScanner Protocol Analyzer is an application for monitoring
and analyzing low-level network traffic received by a network
interface. A free trial edition of the LonScanner tool is included
with the Mini EVK Evaluation Kit. You can also download a free
trial edition from
www.echelon.com/lonscanner . The trial edition
runs for a limited time and throws away some of the received
packets. You can order a LonScanner activation key to remove the
time limit and unlock the full functionality.
