摘　　要：介绍工业控制领域中iFIX的安全机制 ,分析了用户、用户组、安全域和应用属性及其相互关系。阐述了iFIX安全的局限性在此基础上提出了基于iFIX的工业控制网络三层安全模型。该模型具有符合工业安全要求、实时数据通畅可靠、可扩展性好、部署方便等特点 。The safety mechanism of iFIX in industrial control area is presented. The attribution of user; user group; satety domain and application as well as their correlation are analyzed. On the basis of description on the limitation of iFIX safety, an iFIX based three-layer safety model of industrial control network is stated. This model meets industrial safety requirements, keeps real time data unobstructed and reliable, offers better expandability and ease configuration. Excellent results are obtained in practical application.
