In my project I need to configure communication over IEC61850. I have CI868 communication module on system version 6.1 and I need to communicate with Relay REF541. When I try to import SCD file everything is good except one relay. Before Import starts in TreeView Comparator I can't see IP address only of that relay. After start import is pressed error message showed up with these text: "Error while updating IED B07 (Instance 7) in controller for CI8689 (Instance 1). Object reference not set to an instance of an object".
