Overview
The Allen-Bradley 1747-SDN is a single-slot DeviceNet scanner module designed for the SLC 500 family of programmable controllers. This module is designed for use with SLC 500 programmable controllers, specifically compatible with SLC 5/02 and higher systems, and functions as a DeviceNet scanner, enabling communication between the SLC 500 processor and DeviceNet devices on an industrial network. The module is a Printed Circuit Board (PCB) type, identified as Series B. The 1747-SDN facilitates data transfer between the PLC and distributed DeviceNet slave devices using multiple message modes, making it ideal for legacy automation system upgrades and replacements.
Key Features
- Multi-Mode Messaging: Operates in slave mode, handling Polled, Strobe, Change-of-State, and Cyclic I/O configurations.
- Pass-Through Bridge Configuration: Acts as a bridge in pass-through configuration, allowing connection to a separate DeviceNet network.
- Extended Node Support: Supports configuration of up to 63 nodes at a baud rate of 125 Kbps.
- Status Indicators: Front panel includes LED status indicators for module and network status, and LCD display for module address and error indication.
- High Voltage Isolation: Provides 30V circuit isolation tested at 500V AC for 60 seconds between DeviceNet and backplane.
Technical Specifications
The module integrates seamlessly into the SLC 1746 backplane and delivers reliable DeviceNet communication for industrial control systems. Operating temperature ranges and power consumption are suitable for standard industrial environments.
Typical Applications
- Legacy SLC 500 system upgrades requiring DeviceNet integration
- Distributed I/O control networks with DeviceNet-capable field devices
- Industrial machine automation with networked slave device communication
- Process control systems requiring multi-node device coordination
- Manufacturing and assembly line automation networks
Compatibility & Replacements
Compatible With
- Processors: SLC 5/02, 5/03, 5/04, 5/05
- Chassis: SLC 1746 backplane (1746 Backplane Communication)
- Network: DeviceNet protocol at 125 Kbps
- I/O Devices: Up to 63 DeviceNet adapter modules and slave devices
Replaces / Drop-In Replacement For
This pass through feature is designed to replace the 1770-KFD, 1784-PCD, 1784-PCID, or 1784-PCIDS DeviceNet connection on the network. The 1747-SDN functions as a primary DeviceNet scanner for SLC 500 systems, directly supporting communication that earlier configurations required external interface modules to achieve.
Works With
- Programming Software: RSLogix 500 software, RSNetWorx for DeviceNet software, version 2.22 or later
- Network Protocol: DeviceNet (IEC 61804-2 standard)
- Message Modes: Polled, Strobe, Change-of-State, Cyclic I/O, and Pass-Through messaging
- Operating System: Windows 95 or later for configuration
