Capital Improvement Program implemented in Phases Over a 16-Year Period.
Casne Engineering provided Detailed Design, Construction Assistance, PLC and SCADA Programming, Start-Up, and O&M Manuals for each Phase
CASNE Engineering assisted The City of Spokane in the process of upgrading their Riverside Park Water Reclamation Facility. It was recognized that without a consistent approach to the design and implementation of the instrumentation and controls portion of the plant, the overall objective would not be realized. Casne Engineering was selected by the City and the Program Management Office (PMO) of CH2M Hill as the Process Instrumentation and Control System (PICS) engineers for all phases of the CIP.
The SCADA system consists of dual servers running Intellution iFIX software serving 24 network View clients on a redundant Ethernet LAN (SCADA LAN). The system also features a Historian server and an additional server that allows City employees to view the plant process screens via the City’s business network. The system also includes a second redundant Ethernet LAN (PLC LAN) that communicates via fiber optics to programmable logic controllers (PLCs) within each process area.
Each process area is equipped with Allen-Bradley ControlLogix PLC. These PLCs provide control, monitoring and information for trending and reporting for each process area. They also provide a communication link to all packaged control system PLCs in each area for control and monitoring. The PLCs are also networked to Motor Control Centers and Variable Frequency Drives in each process area using DeviceNet.
The initial phases of the program involved the development of design and PLC/HMI programming standards to be used with all existing and future projects. The software standards were jointly developed with the City staff and the Program Management Office. Object-Oriented type programming was used to develop both the SCADA and ControlLogix application programs. This minimized development costs for both software platforms as well as provided a consistent framework to aid the City’s staff in troubleshooting issues across different process areas. The PLC software standards also included programming to optimize Ethernet communications between the SCADA servers and the ControlLogix processors.
