The data point editor - PARA module

Data point types and data points can be created and configured in a number of different ways in WinCC OA. With mass configuration, the settings of a data point can be inherited when creating new data points. All data points inherit the settings (configs with the set parameters) of a master data point.

Although it is possible to use ASCII files for importing from external sources, the more convenient option is to work with the PARA module. In the DemoApplication, this module is started by right-clicking on the line containing the following entry:

User Interface -m para

Then select the ManagerStart option in the context menu. To open the PARA module in English, you have to add the entry -lang en_US.iso88591. Double click on the entry User Interface -m para in the WinCC OA console and add -lang en_US.iso88591 after the entry to read: -m para -lang en_US.iso88591. Select the Start option. The PARA module opens now in English.

Figure: Data point Configuration - PARA Module

The following chapters explain in detail how to configure data point types using PARA, how to create data points and edit sample data points, as well as how to set parameters in configs:

• Mass configuration

• Data point types

• Data points

• PARA module

• Data point configs

• ASCII Manager

• ASCII Manager Panel

In WinCC OA, data points can also be created at runtime by Control scripts (see also the CONTROL function dpCreate()).

Configuration data / data points

Configuration data and data points are saved in a separate database. The parameters are actually set via the PARA module (see also PARA module) or by importing data point lists from ASCII files. A command line function as well as a convenient dialog window is provided for this purpose (see also ASCII Manager and ASCII Manager Panel).
