  6. Poll / Response Latency Example Case - Polling Modbus over VSAT Assumptions: - 16 remote sites on one logical channel - 1 poll for digital input values - 1 poll for analog input values Establish TCP/IP socket connection from the SCADA Host to the remote site: 4 seconds Send the poll for digital inputs: 4 seconds Send the poll for analog inputs: 4 seconds Tear down the socket connection: 2 seconds ------------------------------------------------------------------------ Total time to poll one site: 14 seconds 14 sec / site X 16 sites = 224 seconds or 3.7 minutes to refresh all data

  11. Operations Managers’ Comments • “Our poll response cycle time is 12 minutes.” • “If a leak occurs, time is everything!” • “We had two major spills in the last two years. 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?”

  13. 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!
