Selecting PMBus Logging (Figure 58) from the Tools drop-down menu enables the logging of all PMBus
activity. This includes communications traffic for each polling loop between the GUI and the device. It also
includes common operating values such as Vout, Iout, and Temperature for both output rails. The user is
prompted to select a location for the file to be stored. See next screen (Figure 59).
