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.
"Many manufacturers choose CIP networks to create a seamless flow of information, from the smallest device up through the enterprise business system", explains Paul Brooks, European Product Marketing Manager, Rockwell Automation.
"With CIP Motion, the advantages of CIP and Ethernet now extend to multi-axis coordinated motion control applications, further improving machine synchronisation and information flow, reducing installation costs and increasing productivity".
CIP Motion is a strategic initiative from the Open DeviceNet Vendor Association (ODVA) that is creating a distributed motion control solution using only Ethernet/IP, and includes controller-to-controller and controller-to-drive connectivity.

Radical new approach to motion control?
While traditional motion control systems typically have their own proprietary text based programming languages, ControlLogix uses standard 'ladder logic' programming.
This approach will provide high-performance axis-to-axis synchronisation with clock synchronisation jitter of +/-100ns, a flat network architecture using standard unmodified Ethernet and a common configuration and programming environment.
"CIP Motion is the next logical step in expanding the application space served by Ethernet/IP, continuing to deliver the financial benefits of Ethernet/IP experienced by tens of thousands of users worldwide", Brooks continues.
Concept demonstrations for CIP Motion have settled the question of whether the open, standard design of Ethernet/IP can be used for all application types, including the most demanding motion and drive applications.
Rockwell Automation has demonstrated servo drive control with +/-100ns jitter, sharing the network bandwidth with both traditional automation and commercial office style devices using standard, off-the-shelf Ethernet switches.
"The beauty of CIP is its simplicity", Brooks concludes.
"With CIP, manufacturers save time with no special configurations to the networks".
"Information on a network is not abridged or upended in the configuration; it goes to the right place right away".
"Because it is cost-effective and requires less programming and wiring time than other networks, CIP offers an attractive solution today as well as into the future".
