• Whether or not network interface sharing is enabled or disabled.
Using LonScanner with LNS Turbo Edition
If you plan to use LonScanner FX Professional Edition with LONWORKS channels,
you do not need an LNS Turbo Edition Server. However, when used with the
protocol analyzer, an LNS Turbo Edition Server provides several additional
features, including importing device and network variable names, network
interface sharing, and monitoring of IP-852 channels.
With an LNS Turbo Edition Server, you can import device and network variable
names from an LNS network database into the current LonScanner active log.

The IP-852 interface operates differently from L
interface of every device on a L
channel. But, Echelon’s IP-852 devices and routers do not automatically forward
packets to every other device and router on the channel. Instead, they selectively
forward packets directly to the intended destination devices and routers on the
channel. As a result, the protocol analyzer does not receive packets that are sent
on an IP-852 channel from one device or router to another if the source or
destination device is not the computer running the protocol analyzer.
Figure 7 demonstrates this behavior. In the figure, the protocol analyzer is
monitoring an IP-852 channel that contains two devices (named “IP-852 Device
1” and “IP-852 Device 2”). The protocol analyzer receives only those packets sent
between the IP-852 devices and the LonScanner computer (the network paths
displayed in green). The protocol analyzer does not receive packets sent between
IP Device 1 and IP Device 2 (the network path displayed in red).

Logging Data
This chapter describes how you can log packets with the
protocol analyzer, and how you can view statistics related to
those packets. The first part of this chapter describes how
you can configure the behavior of the protocol analyzer while
it monitors a channel and collects packets, including topics
such as setting logging preferences, using the Capture and
Auto-Scroll features, and filtering packets.
The second part of this chapter describes how to access
statistics that are available when you monitor a channel
with the protocol analyzer, including data related to
bandwidth utilization, the types of packets traveling on the
network, and other network statistics.
This chapter also describes how you can use names to
identify the devices and network variables on the channel
that you are monitoring.

Configuring the LonScanner Protocol Analyzer
You can configure the behavior of the protocol analyzer while it monitors a
channel, including:
• Setting logging preferences to control how the protocol analyzer collects
and record packets from a channel.
• Filtering packets to select which packet types are written to the log file.
• Setting the capture and monitor modes to determine whether the packets
collected from the channel are written to the log file, and whether the
protocol analyzer automatically refreshes the Packet Log display as data
is added to the log.
Setting Logging Preferences
You can use the LonScanner Preferences dialog to determine how the protocol
analyzer collects and displays data during a monitoring session. To set logging
preferences, perform the following steps:
Select File → Preferences to open the Preferences dialog, as shown in

Filtering Packets
You can use filters to select the types of packets that are written to the log file.
You can use two types of filters:
• A
global filter
• A
device filter
the network
When the protocol analyzer receives a packet from the channel, it uses the global
and device filter to determine if the packet passes the filter requirements, as
described in
Figure 9.

Start
The packet does not
pass the filter
requirements.
No
No
Does the packet pass the global
filter requirements?
Yes
Have any devices been defined
in the device filter?
Yes
Does the packet pass the device
filter requirements?
Yes
No
The packet passes the
filter requirements.
Figure 9. Filtering Packets
Important: Each time you modify the filter settings for a channel, the protocol
analyzer automatically saves those settings. Thus, every time you connect to a
channel, the protocol analyzer uses the last set of filter settings defined for the
channel.
