ISA-62443系列的这一部分提供了与ISA-62443-1-1（99.01.01）中描述的七项基本要求（FRs）相关的详细技术控制系统要求（SRs），包括定义控制系统能力安全级别SL C（控制系统）的要求。工业自动化和控制系统（IACS）社区的各个成员将使用这些要求，以及所考虑系统（SuC）的定义区域和管道，同时为特定资产开发适当的控制系统目标SL、SL-T（控制系统）。

This part of the ISA-62443 series provides detailed technical control system requirements (SRs) associated with the seven foundational requirements (FRs) described in ISA-62443-1-1 (99.01.01) including defining the requirements for control system capability security levels, SL C (control system). These requirements would be used by various members of the industrial automation and control system (IACS) community along with the defined zones and conduits for the system under consideration (SuC) while developing the appropriate control system target SL, SL-T(control system), for a specific asset.
