We designed and installed a new Supervisory Control and Data Acquisition (SCADA) system, including five programmable logic controller (PLC)-based control panels, at the Village of Mount Horeb Water Pollution Control Facility. We also installed a radio telemetry system to allow for monitoring and control of ten remote lift stations.
We installed a secure, fiber optic-based Ethernet network ring dedicated to the SCADA system to connect the various PLCs, human machine interface (HMI) graphics computers, and data storage servers located around the facility. We configured the network to automatically recover and maintain plant communications during hardware and fiber optic cable failures. We established a separate network at the facility for telecommunications equipment and video surveillance system hardware.
In addition, we installed desktop computers and touch screen-based industrial computers embedded in control panel enclosures to provide operators access to process control statuses, setpoints, and trends via HMI graphics software. Servers were installed for managing remote connections and archiving, to-the-second, historical process information for trending and engineering analysis.
Our HMI programmers developed a new SCADA HMI and Historian software interface. We set up the SCADA network to allow operations and engineering staff to securely access the SCADA HMI computers and servers from anywhere off-site using computers, smart phones, or tablets.
