DeviceNet connectivity for servo drives
Rockwell Automation is introducing DeviceNet connectivity to the Allen-Bradley Ultra 100 series of servo drives, making it easy to troubleshoot and modify individual parameters via the network
Rockwell Automation is introducing DeviceNet connectivity to the Allen-Bradley Ultra 100 series of servo drives With a power range 500W to 2 kW, the Ultra 100 can cover a wide range of duties, such as an analogue input velocity servo, a stepper replacement, a master encoder follower or a stand-alone position indexer

Data acquisition for Rockwell Software's RSBizWare
The Historian module extends the reporting, analysis and management capabilities of the RSBizWare foundation by providing a powerful set of tools to analyse a wide variety of time-series data.
Ultra 100 servo drives are easy to use, but DeviceNet connectivity can reduce wiring and installation costs even further, making it easy to troubleshoot and modify individual parameters via the network.
Drive set-ups, commissioning and troubleshooting are simple via DeviceNet and, using the web can be accessed from anywhere in the world.
DeviceNet also allows Routine Condition Monitoring (RCM).
Data can be mapped back to an operator interface such as the Allen-Bradley PanelView and monitored to give warnings of abnormal conditions.
These include alarm generation, if pre-set current limits or over-voltage conditions are exceeded and predictive failure warnings to alert the user to potential component or process failure.
More than 250 different drive parameters on a single axis can be accessed via the network.
An example might be lack of grease on an actuator.
When the increased load on the drive reaches a certain point an alarm is raised although the process continues to run.
Simple operator intervention by applying grease to the component should solve the problem.
Should the worst happen and a device fail, however, Automatic Device Replacement (ADR) means that a replacement can be installed on-line and the PLC will automatically configure it.
Naturally, DeviceNet can also be used to integrate PLCs, drives, operator interfaces, motor protection and other 'smart' devices.
As a truly open network, it allows the user to select the best products from over 300 manufacturers.
When combined with ControlNet as the automation and control layer and/or EtherNet as the information layer, it provides a comprehensive shop floor to top floor networking solution.
The Allen-Bradley Ultra 100 with DeviceNet joins the extensive range of products from Rockwell Automation that feature DeviceNet compatibility, bringing extensive control and flexibility benefits to the drive arena.
