31. Impact of Tighter Control Loop Control limit Digital Analogue Pneumatic Manual
32. Recommended For Fast Loop Response Control in the field usingFOUNDATION™fieldbustechnology is recommended by SGSI for simple and cascading loops, not for complex loops. Major benefits identified by SGSI are reduced process controller loading, reduced network traffic enabling more loopsper segment, aswell as very fast loop response.
33. Proven Technology Reduced Wiring and Installation Greater Reliability Why ? Proactive Maintenance Tighter Control
34. The Need For Reliability The global process industry loses $20billion, or five percent of annual production, due to unscheduled downtime and poor quality. ARC estimates that almost 80 percent of these losses are preventable, with 40 percent largely due to operator error. ARC Insight 10th June 2010
38. Customer Experience FOUNDATION™ FieldbusCIF with inherent backup capability prevented 2 incorrect plant shutdowns,which would have resulted from communication interruptions.
