Introduction
What This Chapter Contains This chapter introduces you to the ControlNet Traffic Analyzer tool.
The following table describes what this chapter contains and where to
find specific information.
Main Structure
of ControlNet The ControlNet Traffic Analyzer tool is a 32-bit Windows  application
running on top of a 32-bit ControlNet Driver. This application is used
to examine, store, and analyze network data on a ControlNet network.
You can view the behavior of frames on the network, test ControlNet
reliability, and make sure that every transmission on the network is
correct.
Information Exchange on a ControlNet Network Link
A ControlNet network link’s most important function is to transport
time-critical control information (i.e., I/O status and control
interlocking). Other information (i.e., non time-critical messages such
as program uploads and downloads) is also transported, but does not
interfere with time-critical messages because of ControlNet’s unique
time-slice algorithm.
On a ControlNet network link, information is transferred between
nodes by establishing connections. Each message sent by a producer
contains a Connection ID (CID). Nodes that have been configured to
recognize the CID consume the message, therefore becoming a
consumer.
