What People Are Saying

Support is number one with us. Everyone wants to look at price, but when it comes down to it if you don’t have the support then you don’t have a product. Control Station has been excellent. I’ve called them at all hours – inconvenient times – and they get right back to me.

Rick Redland, Marathon

We recently evaluated LOOP-PRO against a variety of tuning tools and used LOOP-PRO to tune several interactive PID loops that would go unstable when outside a narrow range of operation. The results were evident: LOOP-PRO handled these difficult loops and allowed us to quickly stabilize control and to implement our MPC strategy. Additionally, LOOP-PRO cut tuning time by two-thirds, utilizing a repeatable and effective tuning method.

Jim Sybrandy, Praxair

We experimented with other tuning software packages to see if they could accurately model our batch dynamics. In order for the tools to work properly, they required us to settle out our process and conduct bump tests starting from a steady state. LOOP-PRO was the only tuning package that could handle the dynamic characteristics of our batch processes.

John Gaines, Evonik

We’ve invested in other tuning products, but they almost always failed to work. They couldn’t model the data well – or at all – because of oscillations or other process conditions. I really like LOOP-PRO as it can handle real-world application challenges.

Mac Teats, CH2MHill

TUNER has proven to be an integral and valuable optimization technology for many of our process customers. Its ease-of-use and high return on investment directly align with our goals for the PlantPAx system.

Is the Harris Index Right for Your Loop Assessment Needs?

Predicting the weather is difficult – just ask a meteorologist. Even with the help of advanced analytics few seem to get it right with consistency – just ask any parent who has dealt with an unplanned snow day. In addition to more advanced tools meteorologists rely on basic measures such as Temperature, Wind Speed, and Atmospheric Pressure. Their continued reliance on these simpler metrics provides food for thought.

What is the Industrial Internet of Things (IIoT)?

If you’ve investigated manufacturing trends recently, then the Industrial Internet of Things (IIoT) has probably caught your attention once or twice. IIoT capitalizes on a range of communication and automation technologies that have been applied in industrial applications for years. With its primary focus on the supply chain and enhancing efficiency, however, IIoT often leaves production staff wondering how plant floor operations will be impacted.

Data Collection Speed is Key to the Accurate Interpretation of Process Dynamics

If you’re old enough to remember silent movies, then you know what it’s like to see the characters seemingly jiggle around the screen. Black spots would randomly appear as the story was told with the help of subtitles. Spots and subtitles aside, these movies appeared jittery due to their slow speed. The slow frame rate - a precursor of data collection speed - resulted in visual gaps.

Using Percent Time in Normal to Uncover Tuning Issues

Even Simple Metrics Such as Percent Time in Normal Reveal Issues that Negatively Affect Performance and Signal the Need for Controller Tuning It’s easy to get tripped up if a shoelace is untied. Just ask any child. While that’s a lesson most learn early in their lives each of us can occasionally slip up and find ourselves at risk.

Using Average Absolute Error to Uncover Tuning Issues

Average Absolute Error (AAE) Provides an Intuitive Alternative to Variance and Simplifies the Assessment of Changes in PID Controller Performance.

Quite simply, things at a manufacturing facility can change for the better or they can change for the worse. [ . . . ]
