Power+Energy needed to upgrade their hydrogen purification systems to introduce a lower priced product and improve reliability. They wanted to modernize the aging control systems based on customer feedback. Power+Energy required easy to use engineering software to minimize development time and costs. They chose Siemens S71214 PLCs and TP700 HMIs which provided the necessary features at a good price. The TIA Portal's single engineering software allowed integrated development of PLC, HMI and networking tags, simplifying programming. Power+Energy found the TIA Portal intuitive and its features helped reduce engineering costs by 30% and control system costs by 50%, improving their order book.
