Protocol Implementation Conformance Statement:
SEL-400 Series Devices
The tables below are as shown in the IEC 61850 standard, Part 8-1,
Section 24. Note that since the standard explicitly dictates which services and
functions must be implemented to achieve conformance, only the optional
services and functions are listed.
Refer to the ACSI Conformance Statements on page R.8.37 for information on
the supported services.
MMS Conformance
The Manufacturing Message Specification (MMS) stack provides the basis for
many IEC 61850 protocol services. Table 8.14 defines the service support
requirement and restrictions of the MMS services in the SEL-400 series
devices. Generally, only those services whose implementation is not
mandatory are shown. Refer to the IEC 61850 standard Part 8-1 for more
information.
