Communicating with a C37.118.1a-2014 protocol device

GPA Products PMU Connection Tester

Hi everyone!

I’m trying to use PMU Connection Tester V4.7.4 to communicate with a PMU Unit, make Siemens Siprotec model 7SJ82. The device support C37.118.1a-2014 protocol version. Do you think it will be possible to communicate this version of the Tester with that PMU unit?. I’ve tried with UDP variant with no success; everytime the PMU closes the communication at the first attempt.

Thanks a lot!

The “.1” standards of the IEEE protocol describe the metrology of phasors, not their broadcast, i.e., data reporting; this is handled by the “.2” versions of the protocol. These are the currently published reporting standards:

IEEE C37.118-2005: Metrology + Reporting in same document
IEEE C37.118.2-2011: Reporting only, Metrology moved to “.1” document
IEEE C37.118.2-2024: Reporting only - standard still pending publication

Note that UDP communications can be tricky - make sure to firewalls allow communications.

Hope that helps!

Thanks,
Ritchie
