Advanced solar tracking function block
Wago Corporation’s free Solar Positioning Function Block (SPFB) increases concentrated solar arrangement effectiveness. SPFB achieves this by enabling dynamic solar mirrors to track the sun’s arc within +0.02o via Wago-I/O-System.

Sunnyside up: For precise east-to-west tracking, SPFB relies on multiple variables and inputs. These include 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 then communicated to a connected WAGO DC Motor Control Module and encoder, or other component (e.g., variable frequency drive) for alignment.
Unlike many traditional sensor-driven systems, SPFB provides remote access and manual panel control by linking to a central PC via Ethernet or Internet. Additionally, an integrated Web server (select Wago PFCs) e-mails PV status/alarms. SPFB also features an inclement weather “stow” feature, positioning panels horizontally (wind) or vertically (snow) to reduce stress.
SPFB was developed in-house utilizing data from the U.S. National Resource Energy Laboratory and U.S. Naval Observatory’s 2011 Astronomical Almanac.
PV Panel Positioning: A free Solar Tracking Function Block is also available. It allows the Wago-I/O-System to align PV panels with the sun, for 30% more energy production that fixed panels.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
