SIMATIC WinCC Open Architecture - Basic system


Most modern design concepts are used in SIMATIC WinCC Open Architecture.
The continuous object orientation sets new standards in SCADA systems. The open concept permits the integration of most different components.
Specific solutions from the automation level up to the operating control and management level are provided.

Object orientiation

Object orientation has become a fashionable term in recent years and is used by many manufacturers as a catchword. However, a substantial reduction of implementation times can only be accomplished in practice if the object-oriented approach is implemented throughout, as in SIMATIC WinCC Open Architecture.

The engineering process of SIMATIC WinCC Open Architecture customers is changed by the object-oriented properties and their consistent, careful utilisation.

  • Engineering costs savings of up to 70 %

  • High degree of standardisation

  • Changed course of project from planning to start-up

  • Staff qualifications can be deployed selectively

  • Greater convenience for project engineer and user

Manager concept

SIMATIC WinCC Open Architecture features dedicated, autonomous program units for all key functions - the managers. A "manager" is a process that is responsible for specific tasks. For example, there is a separate manager for periphery connections, history data storage or for user interfaces.

  • Event-Manager (EV),
    the heart of a WinCC Open Architecture system

  • Driver-Manager (D),
    processes are linked via any number of drivers

  • Data- Manager (DB),
    stores process changes in a high-speed database

  • Control-Manager (CTRL),
    is a dedicated runtime environment that processes programs written in the Control programming language on an event-driven, multitasking basis

  • User Interface-Manger (UI),
    takes care of graphical display of process states

Other managers are available for special tasks (redundancy, distribution manager for distributed systems, web server, reporting, DDE, simulation, etc.)

Client-server architecture

The client-server architecture allows practically unlimited scaling of the system. SIMATIC WinCC Open Architecture is used from small single-site systems to distributed, redundant multi-site systems in a wide range of configurations

  • Multi-user and multitasking system

  • Modular architecture based on functional units, the Managers

  • Communication between the individual processes is based on TCP/IP

  • Functions and loads can be distributed across multiple computers

  • It is possible to mix operating system platforms (e.g. Linux) within a system

  • Completely event-oriented, telegram-based communication

  • Remote client terminals can be linked up by modem
