When Cardinal Glass Industries prepared for a 90-day planned shutdown to perform a cold repair on its Menomonie, Wisconsin, float glass plant, it wanted to make sure the control system would work dependably for the next 15 to 20 years. After considering several automation vendors, Cardinal Glass Industries chose an integrated and fully-redundant PCS 7 control system from Siemens Energy & Automation, Inc. Today, the control system reliably automates the entire “hot end” of the production process and provides the trending, diagnostics, and communications needed to keep the plant running reliably and efficiently.
