Change PMU settings via PDC

Hi folks,

Do you know if it's possible to change PMU settings (as data transmission rate) via PDC - specifically via openPDC? I've seen no example of projects mentioning this feature. In IEEE C37.118 command frame definition there are command words used to sent configuration frames CFG-1 and CFG-2 but does the PDC send these frames or just send a command to PMU send these frames?

The SEL Fast Message Protocol will allow you to specify the frame rate during connection - other protocols do not allow this...  Sending the CFG-1 or CFG-2 commands is basically to "request" configuration from the device - not to set it.

IEEE C37.118 has a "custom" frame type that could be used for this feature but it would be device specific.

Thanks for the answer, Ritchie!
