Scripting languages for simulations in modern SCADA systems

The goal of this research is to present modern SCADA (supervisory control and data acquisition) systems abilities. The first part of this paper concentrates on the SCADA history and shows how SCADA systems have changed since they have appeared. This part also includes structure specification of modern SCADA systems as well as merits and description of scripting languages which are embedded in SCADA software. The second part of this research presents scripting languages abilities based on example of Visual Basic for Applications which are integrated with iFIX Intellution HMI/SCADA Automation Software. All examples come from the author's master thesis which is entitled “The use of SCADA System in Visualization of Medicine Production Process”. The extent of this master thesis was done a visualization system. This system presents a real production process which is implemented in one of the pharmaceutical companies in Lodz.
