Introduction
To display a live Citect project in an Internet browser, you need to combine the content of the
project pages and the current data these pages present using standard, Web-based communication
protocols. To understand the communication architecture for the Vijeo Citect Web Client, it's
easiest to consider the role each of the following components play in achieving this outcome:
•
Citect Web Server - Performs the server-side functionality of the system. It operates by
accepting requests from the client, and providing a response to the client when the client’s
details are authenticated. It then directs a client to the graphical and functional content of a
Vijeo Citect project and the location of the runtime servers. This information is stored on the
Web Server when a Vijeo Citect project is configured as a "deployment". A Vijeo Citect
Web Server can contain multiple deployments.
•
Citect Runtime Servers (including the I/O Server, Alarm Server, Trends Server and
Reports Server) - Monitor the physical production facility and contain the live variable tag
data, alarms and trends that the Web Client will display.
•
Web Client - provides the platform to merge a deployed project's pages and content with
the raw data drawn from the runtime servers. Again, standard Web technologies are
necessary, so the client uses Microsoft Internet Explorer.

1. Architecture
The CitectSCADA Web Client allows the remote viewing and control of a live running CitectSCADA project
through internet explorer. The three components required are:
• Web server (CitectSCADA web server + Microsoft IIS)
• Run time servers (IO and RAT servers)
• Web client (Internet Explorer)
Figure 1: CitectSCADA Communication Architecture
As we can see from the diagram, the WebServer acts as a Fileserver for project files, however the actual
data is still received directly from the SCADA Servers, as per a normal Display Client.
- 5 -
In the following example, the WebServer and SCADA Servers are on the same PC, but this does not always
have to be the case.
Hence, in this example only two PCs will be required:
• Server
o Hosts the WebServer
o Hosts SCADA Runtime Servers
• Client
o A ‘Display Client’ viewed via
Internet Explorer
Retrieves Project files from
WebServer
Receives Comms from
SCADA Runtime Servers
