Could we see the monitor log data on PMBus same as we do in Fusion Digital Power Designer PMBus Logging?

We're driving PMBus through a Host Interface.

Thanks,

Hi Harish

TI Fusion GUI has the pmbus logging function which stores all commands sent to the device. Is this what you are looking for?

This can be enable from Tools->PMbus logging.

You can also refer http://www.ti.com/lit/pdf/slvuaw9 for the details of the each command.

Hi Yihe,

My question is how to see the monitor log when the sequencer PMBus interface is connected to on-board Host Processor instead of Fusion GUI.

Thanks,

Thanks Yihe.

Is "(EAh) LOGGED_FAULTS (MFR_SPECIFIC_26)" the right command for fault history?

yes command 0xEA provides a history of all faults.
command 0xEB and 0xEC coupled together provides a details of each faults.
