Systems integrator Optomation Systems designed an integrated supervisory system for the Sotavento site, based on the Opto 22 SNAP PAC System platform. Utilizing a mix of analog and digital I/O connections, standalone and rack-mounted SNAP PACs connect to electrolyzers, motor generator units, and other plant systems and communicate with this equipment as well as with the plant's legacy SCADA systems. Disparate machinery and instrumentation from vendors such as Hydrogenics, Emerson, and Bauer Compressors are linked to the Opto controllers, which communicate using a variety of industrial protocols, such as Profibus and Modbus. The controllers also aggregate all data and serve it to Sotavento databases for analysis and archiving.
