Over the years SCADA systems have evolved from the basic to extremely complex.
One of the best and most popular systems was "Citect".
This was developed by "Control Instrumentation" in the late 1980's.
Over the years ownership changed several times and finished up with Aveva.
Aveva have their own suite of products and in a process taking several years have managed to kill the Citect brand completely.
The product became "PlantSCADA". The core hasn't changed and the actual versions still increment as before.
