  SAT (Site Acceptance Test) Site acceptance test is test to verify the Automation system like DCS (Distributed Control System) & Subsystems are well connected & communicate with each other without having any Hardware or software failure. SAT activity requires involvement of MAC Contractor, EPC Contractor, Subsystem Vendor.         MAC (Main Automation Contractor i.e., Honeywell, Yokogawa etc.) should prepare SAT procedure & submit to PMT (Project Management Team) for approval during CDR (Critical Design Review). DCS (Distributed Control System) SAT also includes Integration Test with various Sub System or Package PLC (programmable logic Controllers) EPC (Engineering Procurement Construction) Contractor coordinates & manages Integration Test activity with sub system vendors. EPC ensures DCS is ready for SAT Like ensuring all Eng/HIS( DCS Engineering Stations), all HIS(Human Interface Station), All DCS System Cabinets(Pro...

    Ratio control To control 2 valves by 1 controller i.e. 0-48% & 52-100% Honeywell uses Fanout Block which gives 2 or more output Gain and Bias is set in Fanout block it calculates ratio automatically eq y=mx+c m gain C bias To calc gain for eg 0-6.5% & 6.5-100% 100/6.5 = 15.385 gain for first valve bias 0 For sec valve Remaining 100-6.5=93.5 100/93.5=1.0695 gain for second output Bias for second valve 100-1.0695×100 =-6.95 for second valve Barrier PR-Phase Reversal if 0 from field Barrier will output 1 vice versa, LF- LINE FAULT Replace FF device To download DD files open Configuration Studio ->Control Strategy->Control Builder-> Monitor->Import DD files-(files shud b uploaded)?
