One of our TSO customers would like to read the associations of the Utility Network objects with FME directly from the topology tables in order to be able to use this information in third-party systems. Is it possible to get a description of the topology tables of the Utility Network and how the associations are stored there?


One way I see to get this information is to configure a network trace and export the result to a JSON file. However, the customer already has a corresponding FME framework for his legacy system, which he would like to adapt and continue to use.


Do you see a way to support this customer requirement?


Many thanks and best regards,
Jürgen

The association information can be accessed from layer 500001 on the UtilityNetwork feature service AnthonyRyanEQL_0-1713491701328.png

 

or if you have database access you can just read the un_<number>_assocations table

To access the topology or the connectivity of the Utility Network, you must run a trace or export subnetwork and get this information from the json file results.
