Step 6: Enabling the Autobaud Option
If it is desirable to have the Anybus-X automatically determine the network baud
rate, the Autobaud option must be enabled.
•
Highlight the Anybus-X module by left clicking on its icon.
•
Select the
Device
menu option and pull down menu.
•
Select the
Class Instance Editor
option. A pop up Message box appears.
Click on
Yes
. Another screen appears.
•
There are several parts to this screen. Make sure the check box titled
Val-
ues in Decimal
is NOT checked. At the top right is an
Object Address
with 3 text boxes. Set the values in these boxes as follows:
-
Class
set to 3.
-
Instance
set to 1.
-
Attribute
set to 64h.
•
To the left of the
Object Class
section is one titled
Service Code
. There’s a
text box with a pull down selection titled
Description
. Pull down the
selections and select “Set Single Attribute”.
•
The box titled
Data Sent to the Device
is now available. At the far left of
this box enter a “01” to enable autobaud, or a “00” to disable it. Then
click on the
Execute
button.
•
A message should appear in the
Data received from device box
saying the
execution was completed.
Note:
Changes to the autobaud option configuration do not take effect until the
module has been power cycled.
Note:
If the Anybus-X is the only master on the DeviceNet network, DO NOT
enable autobaud. Automatic baud detection requires there to be traffic on the net-
work, there is typically no traffic until the master establishes connections.
