Support is number one with us. Everyone wants to look at price, but when it comes down to it if you dont have the support then you dont have a product. Control Station has been excellent. Ive called them at all hours inconvenient times and they get right back to me.
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.
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.
Weve invested in other tuning products, but they almost always failed to work. They couldnt 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.
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.
