FieldDevices
Human Machine Interface• CRISP, 24 years old• 3800 graphics• Uses VAX workstation and emulation software
• 14 - PC Servers, 19 – Proxy Servers• 100 – HMI Workstations
• OCSD owns the software code• Added features over the years to meet our needs• Programmers reaching retirement age
Human Machine Interface
Programmable Logic Controllers• PLC – Modicon Quantum
• ~44,000 input/output points• 150 – Networked PLC’s• 25+ - Non-NW PLC’s
• 20 Years Old• Processors no longer manufactured• Input/output modules no longer
manufactured in the near future
• Maintainability Plan• Spares in warehouse for replacement and near term future projects• Using next generation Modicon PLC (M580) for new projects
P2-107/J-117B
SP-196 Scope of Work• Define SCADA System Features
• Available SCADA technology• Smart devices and instruments• Integration with business and maintenance systems• Predictive maintenance• Advanced control feature• Historian
• Selection Process• Request for Information (RFI) to Vendors• RFI Evaluation• Vendor Interviews and Pricing Evaluation
• Implementation• System Architecture• Implementation Plan
Future Implementation• SCADA Replacement Project (J-120)
• J-120 will replace the existing CRISP hardware and graphics• Develop new HMI graphic standards• Develop PLC/DCS programming standards• Potentially replace the Wonderware Historian and migrate
the data
• SP-196 Schedule Milestone Dates• Start: April 2018• Select Vendor: August 2019• Completion: December 2019
• J-120 Anticipated to Start: December 2020
Schedule
Consultant Selection
• Three proposals received, two invited to interview• Stantec unanimously selected as most qualified
• Strong technical team performing studying on similar size SCADA system
• Deep understanding of the available SCADA systems• Comprehensive approach evaluating the SCADA systems and
documenting the selection process
Summary of Major Negotiated ChangesIncreased:• Workshops
• SCADA feature evaluation• J-120 vendor scope of work• Compile and document selection process
• Pricing templates
Decreased: • Number of design standards
that need updating
• Training workshop support• Site visit trips with OCSD
