- Module PARA
  Graphical interface for editing datapoints and datapoint types.
- 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 data points and data point types and to configure data points.
- 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.
- Data Point Groups
  The main purpose of grouping data points 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.

Requirements and Installation

Correctly installed WinCC OA version.
To modify the NGA settings, the WinCC OA user needs the authorization level (bit) 4.
For the supported databases PostgreSQL®, InfluxDB®, and MS SQL®, see chapter Software requirements.
For the installation and restrictions of NGA on IOT2050, see chapter WinCC OA Support of SIMATIC IOT2050 Devices.

Note: When re-creating an already created new project for NGA by using the WCCOAtoolCreateDB, the config entry "useNGA = 1" must be removed from the config file as WCCOAtoolCreateDB starts ValueArchive internally and does not expect an NGA project.

Notice: When using NGA in projects with high a database load it is recommended to run the database remotely, e.g. DB Installation - InfluxDB® on a remote system
