Safety PLC Rankings

(www.sea.siemens.com/safety) has the leading North American market share for programmable safety systems (safety programmable logic controllers, or PLCs). VDC reports Siemens has a 33.3 percent market share for safety PLC shipments in North America. Following closely was Pilz Automation Safety L.P. (www.pilzusa.com），密歇根州广州，刚刚超过32％。总部位于密尔沃基的Rockwell Automation Inc.（www.rockwellautomation.com) share was just over 20 percent, with no one else registering more than 5 percent.

J.B. Titus, manager of Business Devel-opment and Standards for Siemens Safety Integrated, says the number one market share ranking follows a three-year development strategy that produced state-of-the art safety technology engineering. As a result, market demand for programmable safety systems, as well as acceptance of safety bus networks, has increased.

该研究的作者VDC分析师吉姆·泰勒（Jim Taylor）指出，安全性PLC市场非常新，总销售额仍然相对较小。VDC在未来五年内在该市场中预测迅速增长​​的销售额。
