Query: OpenHistorian field "ID Code (Access ID)"


Can you please provide the details about ID Code (Access ID) field in PMU settings?
What is the purpose of this field?
What should be the value for this field?

Thanks & Regards

This is the ID code used for IEEE C37.118, it represents the identifier for the PMU in the C37 data frame. Since many field devices supporting C37 will not respond to requests without specifying the correct ID, the openHistorian and other GPA tools often refer to this field as an Access ID.
