Possibly one of the most notable sites in New York City today, the World Trade Center Memorial Fountains help us remember those who perished at the World Trade Center on Sept. 11, 2001. To commemorate those lost, the National September 11 Memorial & Museum at the World Trade Center Foundation was established to oversee construction of a memorial on the site of the twin towers. The memorial opened September 11, 2011.
Delta Fountains implemented the Siemens Simatic S7-300 in the design. The two fountains sit in the footprints of the Twin Towers, and each pool holds 600,000 gallons of water.
Sensors are located throughout the fountains and send temperature, pressure, chemistry and wind data to the PLC. Functions are controlled and monitored with touchscreen HMIs. With Siemens WinCC Flexible software, technicians can operate and monitor the pools from Delta Fountains’ headquarters in Jacksonville, Fla.
Taking a look at one of today’s modern marvels, the U.S. Tennis Association (USTA) Billie Jean King National Tennis Center installed a retractable roof over its Arthur Ashe Stadium. The retractable roof is powered and controlled by Siemens’ programmable logic controllers (PLCs), Sinamics drives with fully redundant regenerative active front ends, Siemens safety modules, and comfort panels.
