Case Study: Italian Waste Water Plant Turns To Endress + Hauser For Control System Automation

The urban and industrial sewage treatment plant, in the Liguria region, is based on the biological action of active sludges in two distinct treatment lines: one for treating the sewage, the other for treating the sludge itself. The control system has been based on a completely open architecture based on the ControlCare Field Controller (FC) by Endress+Hauser. The system may be expanded in future whenever necessary without decreasing performance, while maintaining the same prerequisites for functional simplicity. Thanks to the use of standard Foundation Fieldbus function block technology, the FCs form a single distributed control architecture based on an HSE (High Speed Ethernet) network. The function blocks are interconnected via links constituting the central nervous system for control. Each FC deploys a Profibus DP local digital network (integrated Master PFB DP) and manages the discrete utility signals on local I/O boards.
