Established in 1973, CitectSCADA has grown to become a leading global provider of industrial and facilities automation, real-time intelligence and next generation manufacturing execution systems (MES). Headquartered in Sydney, Australia, CitectSCADA has over 20 offices with representation in Oceania, Southeast Asia, China, Japan, North and South America, Europe, Africa and the Middle East. With a large global distribution network, Schneider Electric's Citect products are distributed in more than 80 countries worldwide.

CitectSCADA Scalable Architecture

Resize your system - up or down - without having to modify any of the existing system hardware or software

Innovative scalable architecture allows your system's architecture to grow with your requirements, while preserving your initial investment.

Many CitectSCADA systems have grown from a single computer to large control systems.

The ability for a single system to grow without changes being made to the configuration enables CitectSCADA customers to be confident in the long-term future of their control system.

Go Large

For very large applications, distributed processing allows you to share the processing over multiple computers.

If your require a second operator interface, just add a LAN and a new computer, and nominate it as a Control Client.

The new computer can share the same configuration, and will receive I/O from the first CitectSCADA computer.

Flexible Architecture

CitectSCADA client-server architecture operates at the task level.

Each task works as a distinct client and/or server module, performing its own role, and interfacing with the other tasks through the client-server relationship.

CitectSCADA has five fundamental tasks which handle:

  • Communications with I/O devices
  • Monitoring of alarm conditions
  • Report type output
  • Trending
  • User Display

Each of these tasks is independent, performing its own processing.

CitectSCADA System Redundancy

CitectSCADA's redundancy will tolerate failure anywhere in your system, supporting full, hot standby configurations.

When communicating with an I/O device, many systems demand redundant I/O server configurations.

To avoid conflict of data, and to maximize communication bandwidth, only the primary I/O server communicated with the I/O device.

Many SCADA systems use LANs to connect the elements, but something as simple as a faulty network card can destroy communication.

CitectSCADA's built-in multiple network support provides full LAN redundancy.

All you have to do is install two (or more) networks; if the primary LAN fails, CitectSCADA will automatically try to connect on the other available LANs with no configuration required.

CitectSCADA Task Redundancy

With CitectSCADA's task based architecture, you get an unrivalled level of SCADA redundancy.

Each of the tasks in CitectSCADA, (I/O, Trends, Alarms, Reports, Display), can be shared with other computers in your system.

This allows you to allocate server tasks to two computers at one time; one as the primary and the other as the standby.

If the primary server fails, the standby will automatically assume the role without loss of data.

When the primary is absent, the clients will automatically access the standby server.

When the primary server is reestablished, it will be resynchronized automatically, minimizing gaps in your data.
