Chapter 4 – Gateway Configuration
This chapter describes how to configure and operate the CDN46X gateway. Reading and writing attribute
values over its DeviceNet interface configure the gateway. 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.
Configure DeviceNet Interface
The DeviceNet Baud Rate and MAC ID Address are set 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
CDN46X 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 CDN46X 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 CDN46X 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 CDN46X 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.

Power Up Gateway
Connect the gateway to a DeviceNet network to power up the gateway.
DeviceNet Status LEDs
The CDN46X gateway has two bi-color status LEDs (
NET
and
MOD
) that indicate operational status.
During power-up, the LEDs cycle through a sequence of alternating red and green. After power-up, the
