Wago claims its Solar Positioning Function Block (SPFB) increases concentrated solar arrangement efficacy, as it enables dynamic solar mirrors to track the sun’s arc within +0.02o via the Wago-I/O-System. For East-to-West tracking, SPFB relies on multiple variables and inputs, including atmospheric pressure, site elevation, azimuth, latitude, longitude, date and local time. Calculations are then paired with the internal clock of a Wago programmable fieldbus controller, “optimizing mirror position”. Data is communicated to a connected Wago DC motor control module and encoder, or other component (e.g., variable frequency drive) for alignment.
