7.2. Device Peripheral Table
- Type: Indicates the origin of measurement
- Channel and Address columns: Indicate the virtual I2C channel and address that are used to access the peripheral through the microcontroller.
- ID (DEV/PDR): Indicates the platform descriptor record (PDR) index; otherwise, indicates the device number (DEV), if any, to be passed to the relevant PLDM command.
- UNC: Upper non-critical value
- UC: Upper critical value
- UNR: Upper non-recoverable value: the threshold for power shutdown1

The table above lists ID (DEV/PDR) (device IDs) based at 0, as shown by the fpgainfo command. However, the PLDM commands use device IDs based at 1. Therefore, when using PLDM commands, you must add 1 to the table device ID to obtain the PLDM device ID. For example, the board power ID is listed as 0 in the Device Peripheral Table, but in PLDM commands the board power ID is 1.
Refer to the Intel Acceleration Stack Quick Start Guide for the Intel® Programmable Acceleration Card with Intel® Arria® 10 GX FPGA for information about the fpgainfo command.
