System Browser
The System Browser displays objects in the building control system through various views. You can search
and filter objects, display object names and descriptions, and drag objects into Trends, Schedules, and
Reports.
History Database (HDB)
Historical data is stored in an access-controlled MS SQL Server database. The System Management
Console lets you create a project History Database (HDB) and link it to the active Desigo CC project on the
main server. The history database is used to log a wide range of user and system activities, such as:
● User and system activities
● Alarms and their treatment
● Faults that have occurred and are handled as batch messaging
● Values that are logged as trends
Project database
The runtime data (process image) and the engineering data are stored in a file-based database in a
subdirectory of the project directory. The data is unencrypted and database access can only be prevented
by restricting access to the database files. The project directory needs to get shared when deploying
installed clients. It is therefore important to restrict access on the
db folder in the project directory to the
Windows account running the Desigo CC main server.
Microsoft SQL Server
Desigo CC uses the Microsoft SQL database software. Microsoft SQL Express is included on the product
installation DVD (Microsoft SQL Server 2008 R2 Service Pack 2, Express Edition, version 10.50.4000.0).
Alternately, you can use an existing Microsoft SQL Server installation (same version 10.50.4000.0). In this
case, the Desigo CC Installer will skip the Microsoft SQL Server installation. In both cases, Microsoft SQL
must first be installed and running on the computer where the Desigo CC main server will be installed.
Microsoft IIS server
A Microsoft Internet Information Services (IIS) server for Web Clients and Windows App Clients can be
installed on the Desigo CC server or on a separate installation (web server).
License Manager
Licensing ensures the operation of the system within the agreed system limits. Only the system is allowed
to change license data.
If a license becomes temporarily unavailable (e.g., due to network connection issues) the system continues
to run fully operational for a grace period. The system continues to check for the license and shuts down at
the end of the grace period, if none of the license checks succeed.
Exceeding the limits of the license (e.g., by integrating more field system data points than stated in the
license) puts the system into courtesy mode. Phases of courtesy mode accumulate until a total duration of
