Client/Server Network

Always up-to-date

In the zenon network data is constantly up-to-date, secure and available for all modules. The sophisticated Client/Server System is based on the standard protocol TCP/IP.

The project server manages all data: This applies to online data like measured values, statuses or alarms, as well as historical data (such as archived measured values, historical alarms and CEL-entries) and also engineered data (pictures, graphics, variable definitions), etc. The server is also responsible for the communication with external systems like PLCs, databases, fire alarm systems and bus members.

The client always receives all data through the network from the server. Server and Client align projects automatically. If the project is changed on the server, the client automatically collects all current data online without having to end the Runtime. This also works in connection with CE terminals, PDAs or on the Web.

This way projects are securely created and kept up-to-date in a convenient manner. Through spontaneous data traffic between server and client, zenon helps to save network resources. Reference data is only communicated if it is really needed by the client and if it has changed. This way only a small volume of data traffic is initiated and the connection also works with a small available bandwidth, i.e. if a mobile telephone is used as a modem.

All zenon modules are adjusted to this network solution. That means that all changes (i.e. in a recipe) are always saved on the server and will therefore be immediately available to all other clients.
