Control system ZAT Plant Suite MP

One could divide structure of control system ZAT – Plant Suite MP to two main parts connected through process communication.

Upper part of the system is created by level arranged in a hierarchical way comprising all tools of operator control and other systems for storing, processing and monitoring of all process data. Interconnection up to plant information and control systems is requested ever more frequently. Today this level is generally applied in computers of PC standard under operating system Windows. Tools of Factory Suite by Wonderware company (representing high technological mean in given branch) are used for creation of single applications in control system ZAT - Plant Suite MP most frequently. ZAT has its experience also with putting into operation of other open vizualization systems (e.g. Reliance by GEOVAP company, ControlWeb by Moravské pøístroje company, etc.). Also own tool ZAT Grafik is available for simple applications.

Lower part of the system, identified as ZAT - 2000 MP, represents level of process control and comprises all tools for performing of control algorithms and connection of inputs and outputs for technological process. Hardware devices and software tools of this level are solved by own development and manufacturing with wide using of open standards and integration of components and solutions of third parties.
