Finally we put a few functions and classes together that we already had, and made a simple, easy to use and jet powerful tool which we would liked to have ourselves ;-) Sadly it did not exist when we would have needed it, so we had to make it ourselves.
A simple tool to access data from an IEC 60870-5-104 device. Just browse the values and send some commands.
There are already a few products out there in this area, but either are they expensive and very complex applications that provide a lot more than you actually need. And are nearly unusable if you don’t know what it is all about. Or they are simply crap.
Here is our approach to this problem: The IEC 60870-5-104 Explorer.
