Hi Rabi,
The SEL devices can send continuous waveform data in a modified version of C37.118.2
Note that the standard does not support waveform data.
The PMU Connection tester will only work with standard C37.118.2-2011 (or 2005) and not the modified version.
For the moment there are no plans to support the modified version.
Thank you,
Christoph Lackner
