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.
