Enhanced sequence management functionality

June 2011 IT in Manufacturing

Rockwell Automation launches controller-based batch and sequencing capability.

Rockwell Automation has extended its PlantPAx process automation system with the new PlantPAx Logix Batch and Sequence Manager. The application solves a wide range of local controller-based batch and sequencing needs, by allowing users to configure sequences directly in the controller through the HMI using a standard interface.

With this feature, the need for engineering intensive custom code for system integrators is eliminated. OEMs can now design a common process control solution for end users requiring local sequencing that can easily integrate into a larger plant wide solution. The Logix Batch and Sequence Manager is ideal for standalone units like mixers, blenders and reactors that require flexibility in the sequence of the process and formulas for the recipe. It is also well suited for common continuous sequencing applications like process start-up or shutdown, grade changes and cleaning control.

Many applications require sequence management capabilities, but the complexity of the process may not be great enough to warrant a server-based batch software package. This solution allows the user to start small, but if at any point the requirements grow, users can simply migrate the Logix Batch and Sequence Manager into a comprehensive software solution like FactoryTalk Batch without costly re-engineering and testing.

Today, most custom controller-based recipe management solutions only allow for set-point downloads to a fixed sequence. As a result, users are forced to change the code when the sequence must change. This not only adds risk to the process, but also significant cost to re-test and validate the system. The Logix Batch and Sequence Manager provides users with a standard configuration tool needed to change both the sequence and formula. In addition, the application comes with intuitive, pre-developed configuration and run time HMI screens for easier control and maintenance.

The application is based on ISA-88 standards, which provide a consistent framework for the application. This consistency helps the end user troubleshoot problems faster and thus increase throughput and improve quality.
