Proficy Process Systems provide a suite of process control, execution and analysis tools, and ERP connectivity. An extensive function-block library for implementing advanced PID control strategies and a multi-variable predictive control engine are included. Process functionality includes high-speed reflective memory, supporting redundancy at the controller, network and I/O levelsat speeds in excess of 2 Gbps. The system supports full redundancy in the PACSystems RX7i controllers (VME-based form factor), and an alphabet soup of device and fieldbus protocols, as well as OPC-based integration of third-party controllers. A historian and change management server includes audit trail functions for control logic and visualization. Integrated Batch Execution and Batch Analysis modules complement production management and ERP connectivity solutions.
