1. MODEL IMPLEMENTATION CONFORMANCE STATEMENT (MICS)
1.1 Introduction
This specification is the Model Implementation Conformance Statement (MICS) and presents
the top-level IEC 61850 data model that has been implemented. The definitions of all used
Logical Nodes and their associated Common Data Classes, components and associated
enumerated values are also included for completeness.
The reader is expected to be conversant with the terminology presented within the IEC
61850 part 7 series of specifications.
1.2 Objective
To provide comprehensive details of the standard data object model elements supported by
the device. The MICS is conformant to the devices associated ICD (Substation
Configuration Language) file, according to part 6 of the IEC 61850 standards. The layout of
the presented tables within this document are conformant to the part 7 series of the IEC
61850 standard specifications with the following exceptions:
• The "Trigger Options" field is not presented
• The "M/O" field is not present as the definitions are as deployed within the model
• An additional column "X" is used to signify ALSTOM custom attributes
1.3 Logical Device definitions
The MiCOM relay implements an IEC 61850 server that can contain one or more Logical
Devices. Each Logical Device contains a data model built from instances of specific Logical
Nodes and must consist of at least an instance of the LPHD Logical Node (which is
responsible for providing physical device information) and an instance of the LLN0 Logical
Node (for addressing common issues across the Logical Device).
The IEC 61850 data model is contained within the Logical Devices detailed in the table
below. All MiCOM devices will name the supported Logical Devices consistently to ensure
that data model variables with the same purpose will have the same name within each
MiCOM server.

1.3.1 IEC 61850 Logical Device data model
The IEC 61850 Logical Device top-level data model consists of instances of Logical Nodes.
The data model name for a Logical Node instance is constructed from an optional prefix
(known as the wrapper), the Logical Node name, and an instance ID (or suffix).
The presented data model is in an alphabetically sorted order, rather than a logical order,
because this is the natural order of the data when presented by a native MMS browser.
(Higher level browsers can of course impart any ordering that they desire).
