Wine is a way to run Windows software on Linux, but with no Windows required. Wine is an open-source Windows compatibility layer that can run Windows programs directly on any Linux desktop. Essentially, Wine is trying to re-implement enough of Windows from scratch so that it can run all those Windows applications without actually needing Windows.





This software implements the IEC60870-5-104 protocol (client side) for substation data acquisition and control via tcp/ip network using the QT UI Framework. It can be compiled on Linux and Windows platforms. It's possible to poll and view data from the remote system (RTU) and also send commands.
