Each time the user launches Desigo CC as Windows App Client, a search for
system updates is performed. If a new version of the system is available on the
web server, the user can choose to update it or continue to use the current version.
Windows App Clients require low latency and low network bandwidth and are
appropriate for Branch Office and Home Office connectivity. Internet use is
supported but requires substantial IT Security measures.
Closed mode is not available on Web and Windows App Clients!
Regulations (such as, UL/ULC) restricts the use of current Web and Windows
App Clients.
Web Client (Browser Client)
This client option is deployed on the intranet with full trust and requires access to
local machines. The system runs in Microsoft Internet Explorer 11 (using https as
communication protocol) and is downloaded on demand each time the user
launches the client as a web application. When working in a browser, the user can
have the same functionality available as those working on an Installed Client or it
can be restricted to have a different access when connected remotely. Web Clients
do not support Closed mode.
Web Clients require low latency and high network bandwidth and are appropriate
for intranet connectivity. Internet use is supported but operators have to accept a
degradation of performance and require substantial IT Security measures.
Due to several security issues in IE 11 we recommend to use Windows App
Client or Flex Client instead of IE Web client whenever possible.
Installed Client
The Installed Client is designed for mission-critical applications, such as fire safety
monitoring or critical process control, where users are focused entirely on
monitoring and managing building systems. In this configuration, UI components
used for Event Management are locked in place and cannot be moved or covered
by other applications; this ensures that critical events are never missed or hidden.
Additionally, they can be monitored from the outside by the computer monitoring
hardware (Comark cards).
Installed Clients can optionally be configured to run in Closed mode where only
Desigo CC and other specifically identified applications can run. In Closed mode,
the workstation is dedicated to running Desigo CC, with access to the Start menu
or other operating system and customer applications available only to
administrative users.
Flex Client
Flex Client is the new generation of client released with V4.0 based on HTML5
technology. It allows end-users to manage the system independently of what web
browser application is used, opening the door to use clients in other operating
systems different to Windows and other devices. The UI has been redesigned and
optimized with the latest UX standards allowing the system to be used also for
touch operation.
1.2.2 Typical System Deployments
The key components of Desigo CC can be deployed in different configurations to
optimally satisfy the requirements of the customer project. Examples of
deployments are provided below.
