  Graphical interface for editing datapoints and datapoint types.
  - Module PARA
  - Datapoint configs, basics
  - Datapoint types for the symbol catalog, basics
  - Rename Datapoints
    - dpRename()
      The function renames a datapoint.
- Common Name Service (CNS)
  The plantmodel editor can be used for building and modifying data structures such as views and trees based on CNS and use them within projects easily.
- Mass configuration
  Mass configuration in WinCC OA redefines the fundamental principles of setting up a project and subsequent configuration of the huge range of data points.
- SQL Panel
  The SQL panel allows you to enter SQL statements to perform queries on current and archive data in the WinCC OA database.
- ASCII Manager
  The ASCII Manager allows you to input and output and thus edit datapoints and data point types and to configure datapoints.
- Correction Values and Laboratory Values
  These panels can be used to change existing values (=correct), query values from and add new values too the HistoryDB and RDB.
- Datapoint Groups
  The main purpose of grouping datapoints is to simplify selection of datapoints and datapoint elements.
- Delayed Alerts
  An alert delay can be configured with delayed alerts. This allows short range changes to be filtered out.

Rename Datapoints

The Rename datapoint panel allows you to rename datapoints:

Open the PARA module and select the datapoint that you want to rename. In the context menu of the datapoint select the "Rename datapoint" option. The option is not displayed when clicking a datapoint type (DPT) or a datapoint element.
Note:
In the figure below, the datapoint does not contain any sub elements. Thus, the datapoint element is the datapoint and you can rename the datapoint directly via the element.

Figure 1. Option "Rename datapoint"

CAUTION:
Refer to the parameter description of nameCheck() for not permitted characters.
Specify a new name and check the checkbox "ASCII Export". The ASCII export option backs up the datapoint type and the datapoint under Project_Path/dpList/<dpName>_<Number sequence>.dpl. The cross-reference search searches for the datapoint name in the current project. Click the "Search" button and you can find out where a manual change of the datapoint name is necessary. Click the "Rename" button.
Figure 2. Rename datapoint Panel
The system checks if the entered name is valid and not already in use. If necessary, an error message is shown and the datapoint name is not changed. When a datapoint is renamed, the datapoint configurations, historical values as well as DP access rights are adopted.
Figure 3. Renamed DP "ExampleDP_Arg1_new"

Note the following limitations when renaming datapoints:

If you rename a datapoint, adapt the new name in the whole application (e.g. in the references to DPs in panels, DPs in the alert screen, DPs in the trend configuration or if a DP is used in scripts or in sumalerts).
The functionality is only available for the DPs of the local system. DPs of a distributed system cannot be renamed.
Internal datapoints may not be renamed.
Master datapoints cannot be renamed.
ASCII backups may only be run on the server.
Datapoints can only be renamed when the DataBgManager is running the DataBgManager runs shortly after the project start – see the log messages in the log viewer).
