How can you ensure control systems are delivering value?

In this post, I would like to focus on how to lock-in the value generated from improving your controller performance. This is another big issue that not many people know about or understand that well. I like to think of it as the “improvement half-life” concept. The concept is that process control optimization work delivers good payback in a relatively short period of time. However, the performance of the controllers, and the value they deliver start to decrease over time.

How much is bad control costing your operation?

In my last post I mentioned I would talk about one of the common problems we see with control systems.

This problem is widespread, and can have a major impact on your costs and revenue. What is this problem I am talking about?

Are people changing your controller settings and messing things up?

Many industries have turned to automation in recent years as a means of cutting costs and improving productivity. It’s an effective way to meet the challenges of high labour costs, lower commodity prices and increased production costs. One of the side effects of the increasing use of automation is that the it has become critical for operations to manage and protect the configuration of their control systems. Take this recent example.

How well are your assets being managed?

The age old adage says “You can only manage what you measure”. In today’s operations, control systems and HMIs are critical to ensure efficiency and safety. So how well are your automation assets being managed? How many controllers do you have? What model are they? What firmware are they running? Where are they in their product lifecycle? When was the last backup taken? Where are the backups stored? If you don’t know the answers to all of these questions, or it takes hours, days or even weeks to find out - then take some comfort in the fact that you’re not alone.
