Optimize Loop Tuning

Enter the number of control loops you need to maintain and indicate if your company has a control performance improvement program, an existing control loop performance monitoring application, and/or control loop auto tuning tools. DeltaV InSight delivers benefits from both improved process performance and reduced engineering time, by providing an integrated monitoring and tuning solution which requires no configuration or maintenance.

Assumptions:

  • Manual monitoring and tuning takes an average of 7 hours per loop per year (2 hours monitoring, 5 hours tuning).
  • InSight monitoring and tuning takes an average of 2 hours per loop per year.
  • Average benefit from improved loop performance is $2,000 per loop per year.
  • Manual tuning will take 4 hours per loop per year without a tuning application.

Calculation:

Benefits (per year) = Reduced engineering time + Improved process

Plants with improvement program but no monitoring or tuning tools:

Reduced time = # Loops * 5 hrs * $/hr

Improved process = # Loops * $2,000 * 40%

Plants with improvement program and monitoring but no tuning tools:

Reduced time = # Loops * 4 hrs * $/hr

Improved process = # Loops * $2,000 * 20%

Plants with improvement program and tuning tools but no monitoring:

Reduced time = # Loops * 2 hrs * $/hr

Improved process = # Loops * $2,000 * 20%

Plants with improvement program and tuning tools and monitoring:

Reduced time = # Loops * 1 hrs * $/hr

Improved process = # Loops * $2,000 * 10%

Plants with no improvement program:

Reduced time = # Loops * 5 hrs * $/hr (cost of starting program)

Improved process = # Loops * $2,000 * 100%
