CDN36X User Manual
revision 1.30
Chapter 4 – Gateway Configuration
This chapter describes how to configure and operate the CDN36X gateway. You configure the
gateway by reading and writing attribute values over its DeviceNet interface. There are a variety
of DeviceNet configuration tools available. Simple configuration tools use GET_ATTRIBUTE
and SET_ATTRIBUTE explicit message commands to read and write attribute values,
addressing each attribute by its
Object
,
Instance
, and
Attribute
numbers. This information is
contained in Chapter 5. More sophisticated configuration tools use EDS files to simplify
attribute configuration. You can configure the gateway using pull-down menus, buttons, and
data entry fields from the gateway’s Electronic Data sheet (EDS) file. Chapter 6 contains a
configuration example using the Rockwell Software RSNetworx
™
program.
Configure DeviceNet Interface
Set the DeviceNet Baud Rate and MAC ID Address using the rotary switches. Configure
switches before connecting to the DeviceNet network. There is either a small triangular
indicator or white indicator on the switch. Use a small screwdriver to align that indicator with
the desired setting. Remove the CDN36X cover if necessary to access the rotary switches.
DeviceNet Baud Rate Switch
Valid settings are 125K, 250K, 500K, or PGM. When PGM is selected, the CDN36X uses the
baud rate saved in its retentive memory. To save a valid baud rate in memory, set the switch to
the desired baud rate and power up the CDN36X for a few seconds. Power down and set the
switch to PGM. You may also write to the DeviceNet Object Baud Rate attribute.

MAC ID Switches
The two MAC ID switches represent decimal numbers from 00 to 99. The LSB switch selects
the
Ones
digit and the MSB switch selects the
Tens
digit. Valid MAC IDs are 00 to 63. Setting
a MAC ID address greater than 63 forces the gateway to use the MAC ID saved in retentive
memory. To save a valid MAC ID in memory, set the switches to the desired MAC ID and
power up the CDN36X for a few seconds. Power down and set the switches to value greater
than 63. You may also write to the DeviceNet Object MAC ID attribute.
