ControlNet Message/Traffic Generator Tool2
Introducing the Tool
Use this tool to:
• construct, edit, and send data packets and messages on a
ControlNet network
Using this tool, you can:
– open connections to different objects and send predefined
messages, data byte(s), or packet(s) individually or in a sequence.
– construct, edit and send data packets and messages. These edited
data packets and messages can be saved to and retrieved
from files. Once you have saved data in a file, you can use
function keys to send predefined packets or messages into the
network one by one. You can also use the play option to send all
the data saved in a file, at once.
If you want to view the messages or data packets being sent on
the network, use the Contr
olNet Traffic Analyzer tool (9220-TA).
• assist in the designing and debugging of ControlNet products
Use this table to become familiar with some of the tool’s terms.

Installing the Tool
1. Insert the tool disk into your computer’s 3.5” disk drive.
2. Create a directory on your hard drive for the tool:
mkdir
tg
Enter
The tg directory is used in TG.BAT. If you create a different directory
for the tool, you need to edit the cnxpath in TG.BAT
(set CNXP
ATH=c:\new_directory). The path sets a DOS environment
variable to instruct the tool where to look for CNXOR.CFG.
This gives you flexibility in placing the file and lets you load multiple
files, in different directories.
3. Change to that directory:
tg
cd
Enter
4. Copy the contents of the tool disk to the directory you created:
copy
A:*.*
Enter
5. Start the tool:
tg
Enter
