System Architecture
Desigo CC can be installed completely on one computer, or configured in a flexible
client-server architecture for building automation and fire safety applications allowing
configurations from small single-seat to large multi-user installations. System compo-
nents can be installed together or on separate devices.
Management Station Application Server
The management station server can be installed on standard server or PC hardware,
in a virtual machine environment, or on a dedicated UL Listed workstation.
A Desigo CC installation can have a single server, or be configured with multiple serv-
ers in a distributed configuration. Distributed servers can be used to distribute pro-
cessing power, to segregate systems by or geographical or departmental boundaries,
or to separate servers used for different disciplines – most frequently to isolate UL/ULC
Listed fire workstations from less restrictive components.
Web Server
A web server is required to use the Desigo CC Web and Windows App Clients or to
host the Web Services API. Desigo CC Web Server is based on Microsoft Internet
Information Services (IIS).
Front End Processor (FEP)
A Front End Processor is an extension to the Desigo CC Server that provides addi-
tional resources to connect subsystems. Additionally, FEP can be used as a bridge to
connect an IIS to Desigo CC.
History Database Server
The History Database Server manages historical data collected from subsystems and
user activities. The Server uses Microsoft SQL to store, manage and maintain the his-
toric data of the system. The Desigo CC Database Service runs on the Desigo CC
Server and connects to a Microsoft SQL Server hosting the History Database (HDB).
