Purpose:
This application note is intended to assist users to setup and configure the
CDN366 DeviceNet ASCII gateway converter module with an Allen Bradley (AB)1747-
SDN DeviceNet master scanner for the SLC500 programmable logic controller (PLC)
series.
The users must have some basic knowledge of hardware and software.
Hardware: CDN366, AB PLC, AB 1747-SDN modules.
Software: RSLinx, RSNetworx, RSLogix500, and Microsoft Windows.
The user must have a basic knowledge of DeviceNet specifications and principles.
Hardware and Software Requirements:
The hardware and software requirement is based upon the application. For this
particular application note, the hardware and software are set up based on the listing
below. Note, the configuration below is meant to demonstrate the CDN366 DeviceNet
module integrated with an AB SLC502 PLC and not intended to ask users to use the same
configuration. Based on application requirements, the CDN366 can integrate with many
brands of PLC (AB, Omron, etc.) or PC based platforms (Synergetic, etc.). As long as a
DeviceNet network is available for a particular application, the CDN366 should be able
to integrate in the network.

Schematic Diagrams:
The electrical schematic diagram figure 1 shown on page 3, CDN366 is integrated
with an Allen Bradley (AB) SLC502. The AB SLC500 four-slot rack system contains a
rack power supply (1747-P1), a PLC processor on slot 0 (1747-L524), and a DeviceNet
scanner module on slot 1 (1747-SDN), an 8 points input module on slot 2 (1746-IV8),
and an 8 points output module on slot 3 (1747-OB8). (For further hardware and software
configurations, please visit Allen Bradley website at http://www.ab.com/ )
The 24vdc regulated power supply is powered the network BUS-(0vdc) and
BUS+(24vdc) on DIP790 board. DIP790 is a DeviceNet distribution board with 1-inline
& 6-outline connections. The DIP790 is connected to an AB 1747 DeviceNet scanner
module, which is tapped into the DeviceNet network. Based upon Open DeviceNet
Vendor Association, Inc. (ODVA) specification, the operational voltage ranges from
11~25 vdc. The nominal voltage is 24 vdc. (For more information on specifications, visit
ODVA home page at www.odva.org.)
The AB 1747-PIC is a communication interface module, which uses RSLogic500
software to interface with a PC. RSLogic500 is a window based ladder logic software
program. RSLogic500 enables the user to upload/download and monitor PLC data.
The AB 1770-KFD is a communication interface module, which enables the user
to communicate between serial RS232 to DeviceNet network. The communication
enables the user to setup, configure and access DeviceNet network information using
RSLinx and RSNetWorx software.

CDN366 Setup & Configurations:
Prior to the setup and configuration of the CDN366 device, the PLC hardware
(power supply, CPU, DeviceNet scanner, I/O modules), software (RSLinx, RSNetWorx
& RSLogic500) and interface modules must be setup and configured first. (For further
information on setup and configuration of the Allen Bradley PLC controller, please visit
www.ab.com)
In this particular example, the hardware and software were setup and configured
based upon page 1 listing. The figures below demonstrate that the RSNLinx and
RSNetWorx are running. The DeviceNet scanner module scanned the network and found
node 00 (master DeviceNet scanner) and node 03 (slave interface module). It is
recommended to setup the DeviceNet master scanner module to MAC-ID 00. The
maximum number of nodes on the DeviceNet network is 64, with a MAC-ID ranges of
00~63.

Register Electronic Data Sheet (EDS) File:
In order to integrate the CDN366 to DeviceNet network, the CDN366 must be set
up and configured first. CDN366 must be disconnected from the DeviceNet network
before configuring the node address and baud rate. Set the DeviceNet baud rate to match
with the network baud rate. Set the Mac ID to an unused node address. The example
below shows that the CDN366 was set at Mac ID 01 (MSD=0, LSD=1), and DeviceNet
network baud rate is at 125Kb.

Connect the CDN366 to the DeviceNet network and click on the “network scan” (Online
icon). The DeviceNet master will scan the network. The CDN366 is not registered.
Therefore, RSLinx and RSNetworx do not recognize the device.
