Online-Computer Link via TCP/IP


PM-OPEN TCP/IP represents a flexible and cost-effective solution for the connection of computer systems (MRP, laboratory, logistic and quality management systems, etc.) and office PCs to the automation and process control levels, offering an attractive alternative to the complex, specially designed solutions necessary up till now. 


PM-OPEN TCP/IP allows the exchange of tags and messages between WinCC and one or more computers (peers) with Windows, UNIX, etc. using the TCP/IP protocol. Another area of application for PM-OPEN TCP/IP is the coupling of several WinCC stations in order to exchange tags or messages or to collect them centrally. In addition, PM-OPEN TCP/IP is suitable for use in redundant WinCC configurations.

The integration of Visual Basic for Applications (VBA) provides PM-OPEN TCP/IP with an ideal development platform for the implementation of customized IT solutions. SIMATIC WinCC and PM-OPEN TCP/IP therefore provide a central information interchange for local and company-wide IT integration, for example the integration of the automation level in MES or Office applications.

Security information

To ensure the secure operation of a plant or machine it is also necessary to take suitable preventive action (e.g. cell protection concept) and to integrate the automation and drive components into a state-of-the-art holistic industrial security concept for the entire plant or machine. Any third-party products that may be in use must also be taken into account.
