Optimizing your HMI - Taking time to reevaluate workstations and interfaces can uncover countless ways to increase performance, optimize efficiency, and boost profitability.

Video: Making your plant performance reporting more interactive - What will tomorrow’s “morning meeting” look like? ABB gives a preview of what’s going on in the lab and what your future HMI may look like.

Siemens’ SST 5-5000 steam turbine (foreground), SGen5-3000W generator, and SGT 5-8000H gas turbine at Irsching Unit 4 power plant. Courtesy Siemens EnergySiemens gas turbine breaks 60% efficiency barrier- Two separate performance tests—one by German technical certification agency TŨV—officially confirmed 60%+ net thermal efficiency for Siemens’ H-class gas turbine, while producing nearly 600 MW electrical output in combined-cycle operation at the Irsching Unit 4 power plant near Ingolstadt, Germany. This officially verified record achievement comes ahead of other gas turbine manufacturers pursuing the same high-efficiency goal.

Adding Ethernet protocol options - If your device has to be able to communicate using more than one industrial Ethernet protocol, the number of options is growing.
