GEP integration

rviscardi · March 1, 2019, 10:27am

I have a program developed (in Python) a few years ago that reads data from OpenPDC using the C37.118 protocol; I am trying to understand if it is possible to do the same thing using the GEP protocol instead of C37.118. In openPDC manager I saw that there is a separate configuration for input and output streams, but I see that for output streams you can only choose between three protocols: C37.118, PDCstream and IEC 61850; I don’t see any reference to GEP. My first question is: what do I have to do to enable GEP on the OpenPDC?
Reading a document (found online) entitled “gep-use-tutorial.pdf” I discovered that the first step to enable data exchange is the creation of an authorization request (SRQ file). As far as I know, however, SRQ files can only be created by Windows Server; does this mean that the client that will act as subscriber can only be a Windows machine? And if I want to use a Linux machine as a subscriber, how should I create the authorization request file?
Another doubt concerns the implementation of the API to be written to retrieve data through GEP: is it possible to use cython to integrate them into the existing Python program? Is there an example code that can help me in my work?

Trying to understand if GEP was already active I tried to use the tool “GEP Subscription Tester” (GSF Graph Lines) on the Windows Server 2008 R2 Enterprise where OpenPDC was installed (server and manager version = 2.6.13.0), but at every start the tester crashes. Below is the content of the output_log file:

GEP is an independent protocol for data exchange. API’s exist in C#, C++ and Java. Currently GEP is in the process of becoming a standard, IEEE P2664.

See the folllowing for more information:
