By linking ergonomics, navigation, and design, new HMI systems are able to display complex processes in a way that is easy for the user to understand and manage. The new OMAC standard goes one step further by defining a common look and feel between operator panels in packaging plants.
That's a new twist I was not aware of, Ann. I didn't realize the decision making was shifting to lower-cost operators. I knew vendors were relieving plant operators of the original programming that used to be part of running a plant, but I didn't realize that meant non-engineers had their hands on the controls.
Rob, my understanding is that better, more use-friendly HMI systems are key for both control engineers and operators. There's a shift underway to put more decision-making into the hands of lower-cost operators rather than engineers, which is made possible by more automation of functions and databases that experienced engineers used to do, as you've mentioned several times. This is also being facilitated by better HMI systems.
I agree it is a good thing, Ann, especially as systems are becoming increasingly complex. I would imagine this becomes a more manageable world for control engineers -- greater complexity, simpler interfaces and less original programming.
HMIs are an interesting, sometimes overlooked area of focus for software/display technology improvements. Yet they play a vital part in what happens on the factory floor, and how well, and how quickly, operators can adapt to, or fix, problems in process control. It seems like improvements have been ongoing for a really long time. It's good to see that some kind of standardization is finally arriving, at least on packaging lines.
It's actually amazing to me that there hasn't been a common HMI look and feel and standards prior to this kind of effort--or at least one that has any teeth. Coordinating that diversity must be a bear for organizations to manage let alone impeding worker productivity. Why has it taken so long to push standards?
It's good to see yet another step toward standardization on the factory floor. This is one more step away from hodge-podge world of plant automation. I would guess this will also give control engineers some relief from the daunting task of original programming.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
