Integrated Architecture Simplifies Motion and Machine Control
Single, scalable programming environment. Along with a common control
engine, the Logix platform uses a single programming software package, RSLogix
5000 from Rockwell Software. Once again, this eliminates the need to purchase
and maintain separate motion, sequential, and drive programming tools. The integrated
motion instructions in RSLogix 5000 eliminate the need to write and coordinate
two programs on different controllers, simplifying the application programming
and reducing engineering costs.
Plus, shared development tools allow for the reuse of engineering resources.
If a company needs to scale from one feed line to three, for instance, it's
as easy as adding the necessary processors and copying code from one to the
next. In a matter of minutes, the programming is complete. Having a scalable
architecture allows a company to eliminate repeat work and retraining, significantly
minimizing design efforts.
Integrated recipe management. Like the evolution to electrical machinery,
recipe control is another packaging advancement that has compressed changeover
time. In brief, recipe control allows companies to sidestep the repetitive process
of tuning machines during a line change by saving and managing multiple settings.
That way, the switch from a two-inch bag to a three-inch bag on a VFFS machine
is a push-a-couple-of-buttons task, not an engineering design function. But
once again, recipe management has been a stand-alone function with its own controller
and software package.
In the Rockwell Automation Integrated Architecture, engineers can manage recipes
within the Logix platform using an AllenBradley PanelView for operator interface
or in more complex systems RSView or RSBatch software. The number of recipes
stored is limited only to the memory of the processor. By integrating this function,
the interface between recipe and motion control lies on the same backplane.
So the delay between accessing a recipe to action is reduced. Which amplifies
speed, which augments performance and so on.
Common HMI platform and networking services. With motion, recipe, and
sequential control split, many end users are forced into several HMI solutions.
They are forced, as a result, to maintain software licenses and expertise for
either different companies or different software packages, depending on the
size of the application. Bridging the gap between the platforms increases training
costs, decreases productivity, lessens connectivity, and reduces the ability
to customize.
Rockwell Automation developed its ViewAnyWare strategy — the visualization
component of Integrated Architecture — to deliver a unified and scalable
suite of monitoring and control solutions. All ViewAnyWare products are platform
independent and built on a central configuration environment, RSView Studio.
This makes way for a significant cost reduction and improvement in development
time, plus an ability to reuse applications on different platforms in order
to meet new requirements.
In terms of communication, NetLinx is the open networking strategy for Integrated
Architecture. Designed for industrial applications, NetLinx networks - DeviceNet,
ControlNet and Ethernet/IP — provide a common set of services, enabling
the user to: exchange data for fast and precise control; configure systems and
devices; and collect data for trending or analysis.
System bottlenecks are eliminated because NetLinx leverages producer/consumer
network technology to provide a high performance, deterministic, and distributed
solution. Within a Logix chassis, this flexible architecture permits multiple
processors, networks (including SERCOS) and I/O to be mixed without restrictions.
And as your system grows, ControlNet or Ethernet/IP provides the link to distribute
control to additional chassis. With NetLinx, the right data is available at
the right place at the right time.
