Types of Management Station

The Desigo CC software has a client-server architecture, in which a server component handles all interactions with the field networks and devices installed on the site, while the clients provide the user-facing application that operators interact with.

The computers running the various components of the Desigo CC software are referred to as stations.

Server (required)

The computer that runs the server component of Desigo CC. It hosts all the data of the installation (the project databases) and connects to the field networks and subsystems of the building-control site. Also referred to as the Main Server.

The Desigo CC client application is also installed on the server station, so that this computer can function as an all-in-one management station.
There can only be one server station.
The server station can optionally host an IIS web server.

Client (optional)

An additional, separate computer on which the Desigo CC client application is installed. Also referred to as an installed client.

There can be multiple client stations, allowing multiple operators to manage and supervise the same site.

FEP (optional)

Front-end processor. An additional, separate computer that is used for load-balancing the network-based processing for a system.

There can be multiple FEP stations.
The Desigo CC client application is also installed on the FEP station.

Web Server (optional)

A separate computer hosting an IIS web server component, which enables the functioning of web clients and Windows app clients. This station can be dedicated to that purpose, or it can be optionally configured to also operate as a FEP or client station.

Information

The IIS web server can also be hosted on the server station, in which case this separate web server station is not needed.

Web Client

A computer that is used to access Desigo CC as a browser-based web application, typically over an intranet. It allows access to local resources only. No software is actually installed on the computer. The first time the user accesses the web client, they are required to install the web application certificate.

Web clients can be anonymous, or identified with a host certificate.

Windows App Client

A computer used to access Desigo CC as a light application, downloaded and installed on-demand directly from the Internet Explorer browser. Once installed, it looks like the standard Desigo CC client software, but allows access to local resources only. Each time the user launches the Windows app client, a search for system updates is performed. If a new version is available, the user can choose to update it or continue to use the previous version.

Flex Client

A computer or mobile device is used to access Desigo CC as a browser-based web application. No software is actually installed on the computer or mobile device. Supported mobile devices have a minimum screen resolution of 640 pixels.

Flex Client can be anonymous or identified with a host certificate.
