U.S. East Coast City Installs Second Siemens SCADA System
Siemens' scope of supply will include SCADA system hardware and software application engineering, facility-wide instrumentation and controls loop drawing documentation, and project management coordination. SCADA system factory staging and testing will be included as part of the contract, as well as a formal customer/city factory witness test. Field service support will include onsite installation supervision, field readiness testing, system start-up and commissioning and a formal customer/city test for final SCADA system acceptance. Siemens will also provide Meriden's operations and maintenance personnel with onsite formal training in the use, maintenance and troubleshooting of the pollution control facility's new SCADA system.
The system's design will provide dedicated control locally at six pollution control facility processing areas that will all communicate back to a central data processing area over a standard process control network. Meriden, its consulting engineer Metcalf & Eddy (Wallingford, Conn.), and its general contractor Carlin Contracting Co., Inc. (Waterford, Conn.) also required that the pollution control facility's SCADA system be able to locally interface with third-party Programmable Logic Controller (PLC) systems and provide a facility-wide Ethernet communication-based Human Machine Interface (HMI) system.
Siemens' SCADA system control and monitoring functions include operator interface process graphics, alarm summary display and reporting as well as real-time and historical trending. Meriden will be able to use the SCADA system's in-plant alarm functionality concurrently with Siemens' standard alarm paging software to provide configurable real-time alarm paging over the city's third-party paging system. In addition, the SCADA system will also provide operational and regulatory reports and logs in Microsoft Excel format for real-time and historical data.
