Overview of the Example Applications
The LonTalk Stack Developer’s Kit includes three example applications that are
stored in the LonWorks\LonTalkStack\Examples directory. You can build
these example applications with Microsoft Visual Studio 2008, and then run
them on Windows. To run the examples, you must install OpenLDV 4.0, which
you can download for free from the Echelon Web site at
The following table describes these three
example applications:
Function
Description
SimpleLtDevice
Simulates a voltage amplifier device. This device receives
an input voltage value, multiplies the value by 2, and
outputs the new value.
This simulated device connects to a native LonWorks
channel via OpenLDV 4.0 (or later), using a standard
LonTalk network interface.
This example requires a Layer 2 network interface such
as the Echelon U10 USB Network Interface or PCC-10,
PCLTA-20, or PCLTA-21 network interface card. This
network interface cannot be shared with the OpenLNS
Commissioning Tool or any other application.
SimpleIp852Device
Identical to the SimpleLtDevice example, but it
connects to an IP-852 channel.
To connect the SimpleLtDevice to an IP-852 channel,
you need to install the Echelon IP-852 Configuration
Server (you can download this app for free from the
Echelon Web site at
).
In the IP-852 Configuration Server, you will define the
IPv4 address and port number of the
SimpleIp852Device and any other IP-852 devices that
it communicates with.
For example, to test the SimpleIp852Device with
OpenLNS CT, you can define an IP-852 channel that
consists of two IP-852 devices: the SimpleIp852Device
and OpenLNS CT.
