6 DMTF is a not-for-profit association of industry members dedicated to promoting enterprise and systems Management and interoperability. platform Level Data Model (PLDM) Base Specification DSP0240 6 DMTF Standard Version Introduction 86 87 88 89 90 91 92 93 This document describes base protocol elements of the platform Level Data Model (PLDM) for the purpose of supporting platform -level data models and platform functions in a platform Management subsystem. PLDM is designed to be an effective interface and data model that provides efficient access to low-level platform inventory, monitoring, control, event, and data/parameters transfer functions.

7 For example, temperature, voltage, or fan sensors can have a PLDM representation that can be used to monitor and control the platform using a set of PLDM messages. PLDM defines data representations and commands that abstract the platform Management platform Level Data Model (PLDM) Base Specification Version DMTF Standard 7 platform Level Data Model (PLDM) Base Specification 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 1 Scope This Specification describes base protocol elements of the platform Level Data Model (PLDM) for the purpose of supporting platform -level data models and platform functions in a platform Management subsystem.

8 PLDM defines data representations and commands that abstract the platform Management hardware. This Specification defines the following elements: the base platform Level Data Model (PLDM) for various platform functions a common PLDM message format to support platform functions using PLDM The PLDM message common fields support the identification of payload type, message, PLDM type, and PLDM command/completion codes. 2 Normative References The following referenced documents are indispensable for the application of this document.
