Emerson is expanding its DeltaV Automation Platform with the DeltaV version 15 Feature Pack 3 update for its distributed control system. Users now have access to the infrastructure for the IQ controller — a fault-tolerant, modular, software-defined controller deployed in a server-based environment. DeltaV PK Controller now supports S2 system redundancy alongside support for Profinet S2 devices to accommodate process changes more easily. Feature Pack 3 also adds version control for DeltaV Live. Users can check graphics in and out for customization, analyze who made changes to graphics and other human machine interface elements and why.
