  • Upload configurations to WCC Lite device. App checks if there are no errors in your WCC Lite excel configuration file and converts excel configurations to .json file. Excel file → validation→ .json file.
  • Debug various protocols.
  • Create IEC 61850 protocol client and server model from .icd, .scd or .cid extensions.
  • Create excel configurations for IEC 61850 protocols.

Connecting WCC Lite

WCC excel utility has a debugging tool. This feature helps to track protocol service process and monitor events in real time. If protocol does not work properly (e.g. no communication between devices, data is corrupted, etc.), a user can launch a debug session and find out why the link is not functioning properly


Step 1. Use dropdown menu tab to select a protocol you want to debug.


Protocol selection tab

Step 2. Click on Scan configurations to validate protocol.

Step 3. Click on Start session

Debugger logging

There is an option to store debugger log to a file. Thick the box before starting a session.
