Rockwell Automation Further Expands DeviceNet™ Networking Capabilities for Allen-Bradley® POINT I/O™

July 112003
Expansion adapter provides advanced networking capabilities to a broad range of industrial devices

MAYFIELD HEIGHTS, July 10, 2003 — With its newest addition to DeviceNet™ options for the Allen-Bradley® POINT I/O™ product family, Rockwell Automation continues to offer users a cost-effective interface for highly distributed architectures in applications requiring expanded high-speed access to plant-floor data and a significant reduction in wiring. Coupled with POINT I/O, the 1734-ADNX DeviceNet network interface adapter with subnet expansion provides control, configuration and data collection capabilities for a broad range of industrial devices.

“In the world of DeviceNet, this is the first expansion product of its kind,” said Jim Iubelt, POINT I/O product manager, Rockwell Automation. “The 24 Vdc adapter offers exclusive features to increase the reach of DeviceNet from 500 meters to 1,500 meters and, depending on the scanner capability, from 63 nodes per DeviceNet scanner to more than 126 nodes,” he added.

The 1734-ADNX features two DeviceNet network connections for POINT I/O users. The top connector on the 1734-ADNX connects the adapter to the main DeviceNet network and to a controller scanner module. The lower connector on the 1734-ADNX connects the adapter to a DeviceNet subnet link and products that comply with Open DeviceNet Vendor Association (ODVA) requirements. Subnets are created by dividing a network into interconnected, but independent, segments or domains and are used most often to improve performance and security.

Integrating a DeviceNet subnet link into the 1734-ADNX offers a cost-efficient option when buying considerations include:
· Upgrading and expanding an existing system; 1734-ADN users can simply replace their system with the 1734-ADNX and add a DeviceNet subnet.
· Increasing the distance between a device or sensor and the controller; 1734-ADNX users can double the physical length of their Logix™-based DeviceNet system and reduce long wire runs from field sensors/devices to a single network link by adding a node that is capable of interfacing to devices up to 500 meters from the 1734-ADNX.
· Increasing the node count connected to a DeviceNet link scanner; users can add up to 63 nodes via the DeviceNet subnet to the overall device capacity of the Logix control system, reducing the number of DeviceNet scanners and overall cost of the control system.
· Isolation of manufacturing zones from the main DeviceNet trunk network; this allows users to troubleshoot sensors/devices in smaller groups, ultimately increasing the troubleshooting accuracy and decreasing downtime.
· Bridging multiple DeviceNet links to each other; for example, the main DeviceNet trunk can be configured for Change of State (COS) operation, and the 1734-ADNX DeviceNet subnet configured for Polled. This allows the controller to react more quickly to time-sensitive and major control component system requirements.

The 1734-ADNX supports the Allen-Bradley Logix Architecture by giving users the flexibility to easily integrate non-I/O devices into a Logix system on DeviceNet. It also supports Auto Device Replace (ADR) functionality by maintaining Media Access Control Identifiers (MACIDs) and configuration parameters in its own memory, and not in the DeviceNet scanner. The 1734-ADNX DeviceNet network interface adapter for POINT I/O is available immediately.
