Hello everyone,  
Does anyone know if there is already any information on whether the GPA programs openPDC and openHistorian will be updated to work with the 2024 version of IEEE C37.118.2, and when this will happen?

We do not have an immediate timeline for this, but it is planned. User demand will likely drive the scheduling.

Thanks,  
Ritchie

Do you happen to have a use case for this protocol?  
as far as I know no Vendor supports it at this point. If you have a PMU that does we would love to learn about that. We may consider moving up the timeline if vendors start supporting the protocol.
