Rockwell PID Execution Time: the Difference Between Continuous and Periodic Tasks
Have you ever seen an Integral Term on a PID controller that seems an order of magnitude larger or smaller than what should be used? Often, the issue stems from the method in which logic is executed on the Process Automation Controller (PAC).
Read MoreWhat is Process Gain? Why is Process Gain important when tuning Processes?
Professionals who tune PID controllers using manual methods tend to agree that understanding the Process Gain of their system is of the up-most importance. Among industry practitioners the Process Gain is often referred to as the “how far” or even the “sensitivity” variable and yet these descriptions can be rather vague to beginners.

Here’s the problem: The typical paper mill operates 100s of PID control loops and maintains an even larger quantity of production assets.
Read MoreWhat to Learn from a Plant’s Frequency Data
If you’re old enough to remember the Internet browser called Netscape, then you may remember the company’s CEO – Jim Barksdale – who once quipped: “If we have data, let’s look at data. If all we have is opinions, let’s go with mine.” Fortunately for those that come to this blog there’s typically sufficient amounts of data. That said, a question often raised relative to a plant’s process data is: What gems are hidden in it?
Read MoreHow Does Loop Monitoring Help with Root-Cause Analysis?
For most individuals, a house is the most expensive asset that they’ll ever purchase. And while living there a homeowner can expect a significant problem or two to arise whether that problem involves a leaky roof, termite damage, or some other costly issue. A downside of such problems is that the damage is typically and irrevocably done before the homeowner encounters the first visible signs that the issue even existed.

Read MorePros and Cons of Higher Order Models
Modeling is a time-tested approach for decoding a process’ dynamic behavior. By understanding how a process responds to change it’s possible to apply an appropriate and timely counter measure. Two common applications of modeling are 1) PID controller tuning, and 2) process simulation.
