Compact I/O DeviceNet Scanner Module Module Installation The 1769-SDN module is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution Degree 2(1)) and with circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).
Compact I/O DeviceNet Scanner Module 7 Remove Power ATTENTION ! Remove power before removing or inserting this module. When you remove or insert a module with power applied, an electrical arc may occur.
Compact I/O DeviceNet Scanner Module System Planning Consider the following when planning your system: • The scanner can communicate with up to 63 DeviceNet devices. • The scanner, as a master, can own up to 63 slave I/O nodes. • The scanner can simultaneously be a master and be a slave owned by another DeviceNet master. • A 1769-ECR (right end cap) or 1769-ECL (left end cap) is required to terminate the end of the Compact I/O bus.
Compact I/O DeviceNet Scanner Module 9 System Assembly The module can be attached to an adjacent controller, power supply, or I/O module. For mounting instructions, see “Panel Mounting” on page 10, or “DIN Rail Mounting” on page 12. To work with a system that is already mounted, see “Replacing a Single Module within a System” on page 13. The following procedure shows you how to assemble the Compact I/O system. A D E C B G B F 1. Disconnect power. 2.
Compact I/O DeviceNet Scanner Module 7. Attach an end cap terminator (F) to the last module in the system by using the tongue-and-groove slots as before. 8. Lock the end cap bus terminator (G). A 1769-ECR or 1769-ECL right or left end cap must be used to IMPORTANT terminate the end of the serial communication bus. System Mounting ATTENTION ! During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire strands, etc.) is kept from falling into the module.

Compact I/O DeviceNet Scanner Module Panel Mounting Procedure Using Modules as a Template The following procedure allows you to use the assembled modules as a template for drilling holes in the panel. Due to module mounting hole tolerance, it is important to follow these procedures: 1. On a clean work surface, assemble no more than three modules. 2. Using the assembled modules as a template, carefully mark the center of all module-mounting holes on the panel. 3.
Compact I/O DeviceNet Scanner Module 13 Replacing the Scanner Module within a System The scanner can be replaced while the system is mounted to a panel (or DIN rail). 1. Remove power. See important note on page 7. 2. Remove the DeviceNet cable from the scanner by removing the DeviceNet connector. 3. Remove the upper and lower mounting screws from the scanner (or open the DIN latches using a flat-blade screwdriver). 4.
Compact I/O DeviceNet Scanner Module 11. Restore scanner configuration using RSNetWorx for DeviceNet. IMPORTANT Be sure that the new module has the same node address and baud rate as the module that was replaced. Field Wiring Connections Grounding the Scanner Module This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.
Compact I/O DeviceNet Scanner Module 15 DeviceNet Wiring DeviceNet Connector Grounding Screw Use #14 AWG wire to connect to panel ground. Connect(1) To Red Wire V+ White Wire CAN High Bare Wire Shield Blue Wire CAN Low Black Wire V- 1. Connect the DeviceNet cable to the removable connector as shown. 2. Insert the removable female connector into the mating male connector on the DeviceNet scanner module. 3.
Compact I/O DeviceNet Scanner Module Configuring the 1769-SDN on DeviceNet The 1769-SDN must be configured using a DeviceNet configuration tool. The recommended configuration software is RSNetWorx for DeviceNet (version 3.00 or higher). TIP If your RSNetWorx configuration software does not include the required EDS (Electronic Data Sheet) file, it is available via http://www.ab.com/networks/eds.
Compact I/O DeviceNet Scanner Module 17 Data Organization The scanner uses the input and output data images to transfer data, status and command information between the scanner and the controller. The basic structure is shown below. Refer to the Compact I/O DeviceNet Scanner Module User Manual, publication 1769-UM009A-EN-P, for more detailed information. Input Data Image The input data image is transferred from the scanner module to the controller.
Compact I/O DeviceNet Scanner Module Diagnostic Indicators Indicator Color/ Status Indicates Recommended Action Module Off No power applied to module. Apply power. Flashing Green No Bus Master (MicroLogix or CompactLogix controller) present. Verify module connectors are properly seated. If they are, cycle power to the controller. If this does not correct the problem, replace the controller. If replacing the controller does not correct the problem, replace the 1769-SDN.
