SCADA is an acronym that stands for Supervisory Control and Data Acquisition. SCADA refers to a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data. In fact, choice SCADA system is not very difficult.
First, from the customer side in most cases the choice of management and control system has long been defined, on the same production is typically used one type of SCADA system (at large facilities may be used several different subsystems (eg, one for accounting of electricity, one for gas and one for control systems)). In any case, the customer will try to use the familiar solutions of proven system integrators.
Secondly, system integrators also been determined, and in most cases, have concluded a partnership with one, rarely more, distributor of software and promote and install this products line.
Thirdly, also important the question of popularity and confidence to the system. Large manufacturers will not agree to the installation of little-known systems, in order not to risk a big production. However, the issue price of the license of the product will be not so important, and the range of possible solutions will be reduced at times.
Again, do not forget the support and product development, large companies, developers constantly improving and updating software version, and a small group of enthusiasts that promote their system, can disappear just as it came, leaving his child without a future.
So if you still decided to implement a new SCADA project and turn over a new leaf for a specific task and meet certain budget, then this comparison table will be very useful for you. It contains no fundamentally new information, and based only on data from the manufacturers. In case of inaccuracies, and new data, it will be edited and supplemented.
The main features are shown in several columns for better comparison facilities.
