APACS+®, which represents the next generation of the market's first-ever unified DCS/PLC, is the first automation system to break through the capacity limitations that currently exist in other Windows® NT-based systems. It is also the only system to offer the benefits of open, such as easy interface to third-party applications, with the advantages of a proprietary DCS, such as seamless integration. As the marketplace's first-ever scalable Windows NT-based system, the APACS+ process automation system is extensible from a hundred I/O to hundreds of thousands of I/O with no discontinuity in the architecture. In fact, APACS+ uses all of the same hardware and software for small and large systems in batch, continuous, and critical applications and delivers full redundancy in the system architecture, from control modules through workstations. However, APACS+ goes even further than simply providing a scalable NT system, exploiting open, standards-based technology to ensure that these benefits do not come at the expense of flexibility. This open environment allows users to take advantage of "best in class" components for unmatched capability at the lowest risk. The system's "best in class" components include the industry's first open controller, the most complete implementation of the IEC 61131-3 standard in control strategy configuration tools, and powerful third-party applications, such as Wonderware® Corporation's industry leading process visualization software. Moreover, its field-proven, open technology affords real user choice. Finally, APACS+ is the only open system to provide a traditional "out-of-the-box" DCS-style framework within an open environment. This framework includes seamlessly integrated controller hardware and comprehensive automation software for easier configuration, enhanced system communication, alarming, and diagnostics. In addition, the framework offers starting points for easier system customization, such as preconfigured control strategies and an expandable shell from which to develop the operator interface.
