IEC61850 adopts abstract communication service interface (ACSI) which is independent to the mapped target network. IEC61850-8-1 defines specific communication service mapping (SCSM) which expatiates how ACSI is mapped to MMS.

• IEC61850-7-2定义了独立于实现网络的IEC61850抽象通信服务接口(ACSI),IEC61850-8-1制定了由ACSI到制造报文规范(MMS)的特定通信服务映射规范(SCSM)。
