With a large global distribution network, Schneider Electrics Citect products are distributed in more than 80 countries worldwide.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.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 IO from the first CitectSCADA computer. To avoid conflict of data, and to maximize communication bandwidth, only the primary IO server communicated with the IO device. Many SCADA systems use LANs to connect the elements, but something as simple as a faulty network card can destroy communication. Citect Schneider Electric Full LAN RedundancyCitectSCADAs 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. Each of the tasks in CitectSCADA, (IO, 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. ![]() 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. The Project Editor is the application where all database changes are made.
