PLDM for Monitoring and control (DSP0248) was defined by DMTF as the management protocol for in-box devices. OCP 3.0 allows for multiple configurations to be used. A PLDM model is presented, allowing managing the different card types, using a consistent modeling scheme based on DMTF DSP2054. This talk covers the different elements in the PLDM schema, their enumeration method and how to use the same schema to address all the different card types defined in OCP 3.0 spec
