EMERSON DeltaV KJ1700X1-BA1 Media Converter

Emerson DeltaV DCS Introduction

DeltaV systems provide powerful, easy-to-use software for designing and operating process controls.

DeltaV utilizes standard Windows functionality to provide a familiar user interface. 

The latest version, DELTAV14 in English and R6 in Chinese, has the number one market share in a variety of DCS markets. 

Its systems are very popular internationally, and it has extensive cooperation with the world's leading petrochemical companies.

The Control Conditions monitored for every control loop and reported in the Overview and Summary displays include:

Uncertain Input. A block’s process variable is bad,uncertain, or limited.

Limited Control. A downstream condition is limiting the control block action; for example, the output is at a maximum limit.

Incorrect Mode. The actual mode of a block does not match the normal mode configured for the block.

Large Variability. A block’s standard deviation and variability index are exceeding their maximum limits.

Process Oscillation. A block’s process variable has oscillatory behavior.

Recommended Tuning. A tuning recommendation has been calculated that significantly improves control.

Device Alerts. Indicates when a control module has one or more devices that have had active device alerts.

DeltaV InSight calculates the percent time that these control conditions exist and eports them as an abnormal condition if the percent time exceeds a defined global limit.

Abnormal control conditions are indicated in overview graphs and summary tables from which the user may drill down on specific blocks for more detailed control performance indices and historical trends.

InSight configuration is automatically updated with the latest configuration. 

DeltaV InSight also performs better because the control calculations are embedded directly in the controller. 

Calculations for control performance, diagnostics, and tuning require a lot of information,which can significantly add to system communications loading. 

Embedded calculations greatly reduce the system communications as compared with traditional OPC data access.

Furthermore, for fast loops, it’s virtually impossible to scan the control loop via OPC fast enough for accurate calculations.
