Description
The Allen-Bradley 1747-SDN is a specialized DeviceNet Communication Scanner Module engineered specifically for the SLC 500 modular control platform. Acting as a high-performance bridge between the SLC 500 processor and external DeviceNet automation devices, this module coordinates seamless data exchange across the network. It interfaces directly with the SLC 500 backplane, utilizing M-file transfers and discrete I/O mapping to transmit real-time process data, diagnostic information, and device configurations.
Designed to optimize industrial network architectures, the 1747-SDN supports up to 64 nodes on a single DeviceNet link while managing polled, strobe, change-of-state, and cyclic messaging structures. The unit features onboard flash backup memory to streamline device replacement and network restoration, making it an essential component for distributed control systems requiring robust peer-to-peer and master-slave communication.
Features
- Supports up to 64 DeviceNet nodes with selectable data rates of 125 kbps, 250 kbps, and 500 kbps
- Communicates with SLC 5/02, 5/03, 5/04, and 5/05 processors via M-file transfers and discrete I/O
- Features front-panel bi-color LED indicators for module status, network status, and I/O status diagnostics
- Includes flash memory for non-volatile storage of scanlist and node configuration data
- Supports UCMM (Unconnected Message Manager) capable devices for dynamic message routing
Applications
- Distributed I/O data acquisition in discrete manufacturing and assembly lines
- Interfacing variable frequency drives, intelligent starters, and sensors to SLC 500 controllers
- Multi-vendor device integration on standardized DeviceNet plant networks
- Material handling and conveyor system network coordination
