→子系统 Subsystem
子系统表述为一个系统对象，该系统对象包含定义了系统所控制操作环境的特征的信息。<ref>IBM's definition @ http://www.ibm.com/support/knowledgecenter/ssw_i5_54/rzaks/rzakssbsd.htm</ref>数据测试用于验证各个子系统配置数据的准确性（例如MA长度、静态速度曲线、…），有一个单个子系统关联了这些子系统，以测试其特定应用（SA）。<ref>{{Cite book|title=European Committee for Electrotechnical Standardization (CENELEC) - EN 50128|last=|first=|publisher=CENELEC|year=2011|isbn=|location=Brussels, Belgium|pages=Table A.11 – Data Préparation Techniques (8.4)}}</ref>
