Wrap-up

Fieldbus Benefits n Engineering n Installation n Operation n Maintenance

Fieldbus Benefits - Engineering n Reduced number of engineering drawings to add well, 92% - ARCO n Reduced engineering time for cabling, marshalling - Lurgi n Reduced hardware documentation - Lurgi n Configure field devices from central workstation - Lurgi n Reduced configuration time to add well, 90% - ARCO n Reduced configuration time - Lurgi

Fieldbus Benefits - Installation n Fewer field devices and system cabinets - Lurgi, Kaneka n Smaller control room footprint - Lurgi, Bowater n Less wiring and terminations, 69%- ARCO, 60%-Monsanto, also Lurgi, Bowater, Kaneka n Reduced factory checkout, 83% - ARCO, also Lurgi n Less commissioning time - Lurgi, Bowater, Singapore Polytechnic, Monsanto n Consistent calibration procedure - Monsanto

Fieldbus Benefits - Operation n Reduced raw materials - Mitsubishi n Reduced process variability - Lurgi n Stabilized product quality - Mitsubishi n Improved process availability - Lurgi n Expanded view of the instrumentation - Monsanto n Process data includes status - Monsanto

Fieldbus Benefits - Maintenance n Reduced effort for field calibration - Mitsubishi n Eliminate unscheduled downtime - Bowater n Includes self diagnostic tools - Lurgi, Monsanto, Kaneka n Increased reliability due to diagnostics - Mitsubishi, Kaneka n Identify, calibrate, trouble shoot field devices from central work station - Lurgi, Monsanto, Kaneka n Retrofit is easier - Monsanto

Summary of Results Installations of F OUNDATION fieldbus report impressive benefits and significant savings during engineering, installation, operation, and maintenance. Users have also noted the need for more products and services to increase these savings and identified fieldbus issues that need examination.

Issues, Concerns, and Challenges n More types of field devices - Kaneka n Field devices with -50º C, CSA ratings - Syncrude n Additional types of fieldbus cables and terminals - Kaneka n Handheld field configurator - Syncrude n High speed backbone availability - Syncrude n Fiberoptic and radio links - Syncrude n Safety systems - Syncrude

Issues, Concerns, and Challenges n Fieldbus system performance criteria and physical topology - Kaneka n Layout of non-IS, IS segments - Syncrude n Documentation, I.e. loop drawings, P&IDs - Syncrude n Methodology of factory checkout - Kaneka n Operator and technician acceptance - Syncrude n Control in the control room or field - Syncrude n Alarm handling - Syncrude
