WIRELESS CONTROL SYSTEM

Starting with site trials in 2009, Rotork is extending the capabilities of the Pakscan control system with the addition of a wireless option. The modular nature of the P3 Pakscan master station now allows the user to have the choice of a fully wired loop for control and monitoring, a fully wireless control and monitoring system, or wired control with wireless monitoring.

Utilizing the internationally accepted 2.4GHz frequency, the wireless network card gives the user access to all the standard data available from the wired system, together with the diagnostic and asset management information stored by the actuator data logger and configuration files. It allows easy extraction of these files, which up until now have only been downloadable locally, using hand-held tools.

The wireless system also increases the available node count of each master station to 300, and has a line-of-site operating range of approximately 230 feet (70 meters) indoors and 3,209 feet ( 1,000 meters) outdoors. The use of meshing and repeaters further increases the range to individual field units.

SOFTWARE TO GRAPHICALLY
PINPOINT PLANT INTERACTIONS

Exper Tune’s Plant Triage software includes a new tool that graphically highlights plant interactions. Using the new “Interaction Hot Spots,” engineers can quickly pinpoint the root cause of process interactions, and resolve these upsets to improve quality, energy, production rate, and process uptime.

The browser-based tool is now included with Plant Triage, which monitors all plant control loops and instruments in real-time. Interactions between control loops appear as colored blocks on the Interaction Hot Spots display. Green indicates no interaction, yellow indicates some interaction, and red indicates strong interaction. On a single web page, users can see all of the significant interactions in the entire plant, but pinpointing the interactions is just the starting point.

The Hot Spots display is interactive. Using a slider, users can filter the display to show only the most significant interactions. Simple drop-down menus allow the user to narrow the scope of an effort, and focus, for example, on just a few unit operations.

Users are already reporting successes from employing these interaction tools. According to the software’s developer, one plant in Alabama is now saving over $1 million per year after solving an interaction problem that started in the utilities area.
