Changing the frequency prompts a pop-up window with details of the options Figure 12-6).

After a change is selected, orange U icon is displayed to offer Undo Change option. Change is not retained until either Write to Hardware or Store Config to NVM is selected. When Write to Hardware is selected, change is committed to volatile memory and defaults back to previous setting on input power cycle. When Store Config to NVM is selected, change is committed to nonvolatile memory and becomes the new default (Figure 12-7).

After making changes to one or more configurable parameters, the changes can be committed to nonvolatile memory by selecting Store Config to NVM. This action prompts a confirm selection pop-up, and if confirmed, the changes are committed to nonvolatile memory (Figure 12-8).

In the lower left corner, the different view screens can be changed. The view screens can be changed between Configure, Monitor and Status as needed (Figure 12-9).

Selecting Store User Configuration to Flash Memory from the device pull-down menu has the same functionality as the Store Config to NVM button from the configure screen. It results in committing the current configuration to nonvolatile memory (Figure 12-12).

Selecting PMBus Logging (Figure 12-13) 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. The user is prompted to select a location for the file to be stored. See next screen (Figure 12-14).

Figure 12-13 PMBus Logging

Select the storage location for the file and the type of file. As shown (Figure 12-14), the file is a CSV file to be stored in the directory path shown. Logging begins when the Start Logging button is selected, and stops when it is reselected (as Stop Logging). This file can rapidly grow in size, so caution is advised when using this function.
