The Current State of SCADA Arlen Nipper - Cirrus Link Rob Coulter - IBM How can we apply technology to: • Mitigate environmental risk? • Detect leaks earlier? • Resolve problems faster? • Manage audit and regulation more effectively? Instrumented Interconnected • Run operations more efficiently?

Clean-up of our last spill cost $6,000,000” • “We are taxed on the greenhouse gases we emit so need to calculate and optimize but do not have the capability to effectively do so today” • “SCADA host companies charge for each protocol they attach to the host. The cost is approx $10K/protocol plus 25% maintenance per year. We have 32 different protocols ($320,000 upfront and $80,000 per year)” • “We need better access to our other field devices beyond just the PLC’s” • “How can we provide other lines of business applications with our operational data without compromising the SCADA host application?” *YDKWYDK Future Apps & Integration SCADA Host #2 SCADA Host #1 1 Analytics & BIG DATA Electronic Flow Measurement ERP Mobile Apps 2 3 ? Asset Management & Optimization 4 5 n “Enterprise (IT)” “Operations (OT)” IT || OT Summary Poll-Response SCADA systems were perfectly viable solutions when first developed 35 years ago. They have served the industry well, and continue to do so. But we are entering 2014 and are now challenged with: • Device protocols tied intimately to applications. • A need to significantly reduce critical data update times. • Current network bandwidth consumption limiting additional information. • “One to One” information silos. • “Operational Intelligence” stranded in field devices!
