READ_POUT 1 is copied READ_POUT 2 to 4?

I will work on a contact to help you.

Can you tell what devices, how many of them you are using on the board? Is there any other PMBus Host beside TI Fusion GUI? What TI Fusion GUI version are you using?

The board is XILINX ZC702, so three UCD9248PFC and each of them controls two PTD08D210W(4 power rails).

Cortex A9 can be the PMBus HOST, but it should not submit any commands.
Because TI Fusion works other than READ_POUT, works fine, anyway. But there are CML:"Other Comms Fault" in TI Fusion. Can this relates?

Version is 7.0.11.

I stopped the processor which can be PMbus HOST beside TI Fusion GUI, but nothing changed. READ_POUT_2,_3,_4 looks like READ_POUT_1 copied.
POUT should be obtained by multiplication of READ_VOUT and READ_IOUT.

For example,
at time 27:23.1=> READ_VOUT_1 =0.955 READ_IOUT_1=0.0313 READ_POUT_1 = 0.0298
READ_VOUT_2 =1.004 READ_IOUT_2=0.1094 READ_POUT_2 = 0.0298 <-- it should be 0.0198
READ_VOUT_3 =1.808 READ_IOUT_3=0.0313 READ_POUT_3 = 0.0298 <-- it should be 0.0565


The following is Data Log of TI Fusion.READ_POUT_1 to 4 has same value.
