Desigo CC
System Architecture / Server Options
Desigo CC is a flexible full client-server architecture for building automation and fire safety applications allowing configurations from
small single-seat to large multiuser installations.
Desigo CC can be installed completely on one computer, with full server and client functionality. Additional Installed, Web, and Windows
App (ClickOnce) Clients can also be added. Additional system connections can be made through systems installed with a Desigo CC Front
End Process (FEP) configuration. An IIS server for Web Clients and Windows App Clients can be installed on the Desigo CC server or on a
separate installation (Web Server).
The server hosts all the data for the system, while the clients are only for the visualization and the user interaction. The clients provide a
high-resolution interface to all the relevant server data needed for monitoring and to command the installation.

Main Server
A Desigo CC architecture supports one project server: the main server. The main server contains the project database and the software
that monitors and commands the system network. Clients connect to this server to monitor and control the facility. If the same compu-
ter runs Internet Information Server (IIS), the installation provides web clients with access to the facility. Note that the Desigo CC server
installation always includes an installed client too, providing the user interface used to monitor and control the facility. For a small
application it is common to have one single computer acting as server and client, while for medium to large installations, the server PC is
dedicated to server activities only. The main server is the computer where the core system services run, and where the project databases
reside. It has interface connections to the field (either directly or using FEP) and provides a centralized database and other services to the
connected clients. The main server can support a number of clients that are connected using a network (LAN) or Intranet (WAN).
Web Server
The Web Server allows you to access the system using the customer‘s intranet, using a Web browser.
It allows downloading all files required for the Web Client and Windows App Client environments. It provides a system web page to
access the Web Client, the Windows App Client, and the system documentation in the Internet Explorer browser. It also represents the
endpoint of the communication with the System Server.
Front End Processor
A Front End Processor (FEP) is a computer that provides additional connections between building level devices (such as field panels) and
the Desigo CC system.
By providing additional connections to the building level network, a FEP enables load balancing for the network-based processing for a
Desigo CC system.
SQL Server
Desigo CC uses the Microsoft SQL database software. SQL Express is included on the product installation DVD. Alternately, you can use an
existing SQL Server installation (same version 10.50.4000.0). In this case, the Desigo CC Installer will skip the SQL Server installation. In
both cases, SQL must first be installed and running on the computer where the Desigo CC Main Server will be installed. The purchaser of
the Desigo CC must ensure that the MS SQL server is properly and correcly licensed.
History Database (HDB)
The history database (HDB) is used to log a wide range of user and system activities and guarantees storage of the following data:
• User activities in the system
• Alarms and their treatment
• Faults that have occurred and are handled as batch messaging
• Type of values logged in trend
For details about the range of logged user activities and system events please refer to the Desigo CC product documentation.
