IEDExplorer

IEDExplorer is a Windows application that can be used for testing connections to IEC61850 devices (sometimes called IED Devices). It does this by using the MMS (ISO/IEC9506-1 and ISO/IEC 9506-2) communication protocol.

To be able to run this app, it's necessary to have .NET Framework and WinPcap installed. The tool itself is not wrapped in a setup file, so it can be launched even from a USB flash drive or just a collection of portable software. However, it automatically creates files at startup to remember configuration settings.

With a familiar-looking interface that has a clear-cut structure, IEDExplorer has views available for MMS and 61850, along with reports, poll and capture information. The software program gives you the possibility to analyze MMS variables in the tree view, create and delete variable lists, as well as enable and read buffered and unbuffered reports. According to the developer, writing to variables and sending commands are two other supported features but limited.

ISO connection parameters can be set when it comes to the saved IEDs, hostname, TCP port, remote AP IP and qualifier, P, S and T selectors, authentication mode, and other aspects.

The software project is still in beta development stage, so any user feedback is welcomed. It's released under the GPLv3 license, making it free and open source.
