Hi there! Here is the link for the HMI software I have promised you in the previous post. https://sourceforge.net/projects/oshmiopensubstationhmi/ It’s a third release candidate, not fully tested, but I think it’s very usable. Some things might change until the official 3.0 release. The source code is available via a Mercurial repository. Simply download, install and follow the instructions present in c:\oshmi\release_notes.txt. Have fun!
