DeltaV Makes It EasyDeltaV Makes It Easy


We Rethought DeltaV From the Ground Up

q Designed for scalability to address the full range of customer needs

q Built on a base of commercial technology

q Provides for a seamless flow of information from the plant floor to the user’s desktop

q Focuses on ease of use

q Embraces fieldbusses and control in field devices




DeltaV Philosophy

• Designed To Meet Needs of Largest Applications– Easy to Use and Easy to Learn– Flexible approach to system engineering

• PLC Strengths– Rugged hardware– Scalable– Low Cost

• DCS-like foundation– Pre-engineered control structure– Pre-engineered operator interface– Solid Communications (i.e. unsolicited, peer to peer)– Global configuration database

Distributed in runtime system– Integration with host and field systems

Fieldbus Architecture Is Consistently Used by DeltaV and Fieldbus Devices


DeltaV Inspect - Abnormal Situation and Control Performance Monitoring

q Identifies abnormal conditions in field devices and control loops

q No configuration required

q Client / Server architecture allows plant-wide and remote access

q Automatically adapts as control modules are added




Parameters and Attributes Used By DeltaV Inspect

Function Block Inputs and Outputs Provide an Engineering Unit Value AND Status

Function Blocks Support Mode


Mode Attribute: Target (Operator Requested Mode) Actual (Mode of operation)Normal (The designed Mode)Permitted (Modes that may be selected by an operator)

Detecting Incorrect Mode of Operation




Measurement of Process Variability Using Total Vs. Capability Standard Deviation

Time

“Capability” Only Random or Short-Term Variability

“Total”:All Data including Short- and Long-Term Variability
