Purpose
The Pareto (PA) block can accept up to eight inputs and calculate percentages for them.
Features
The Pareto block:
- Is an optional statistical process control block.
- Is a primary block.
- Is a stand-alone block.
- Accepts up to eight inputs from blocks, such as Analog Input and Totalizer blocks, or through operator entries.
- Continually calculates the percentage of the total inputs.
- Maintains two sets of values: one sorted in ascending or descending order; the other unsorted. Unsorted values remain in their order of entry on the Pareto block dialog box.
- Can be used in a chain with exception-based or time-based processing.
