By combining the best of programmable controllers with distributed control systems, the ProcessLogix(TM) system from Rockwell Automation's Allen-Bradley division is said to deliver the next generation control architecture for integrated sequential, motion, process, and drive-system applications. The system is a server-based, distributed control system. Based on the company's ControlLogix architecture, ProcessLogix blends software, hardware, and a global database into a single entity. Process-Logix system uses ControlNet to communicate between the core components. The physical cabling is based on the commonly available RG-6/U Quad-Shield cable and ControlNet taps, providing easy installation and immunity from EMI/RFI. Developers can use hundreds of standard displays such as alarms, trends, history, and reporting for fast set-up. The system also includes an object-oriented custom display builder with a library of commonly used plant equipment. Rockwell Automation, Allen-Bradley, Product Code 4299.
