    en.wikipedia.org/wiki/Distributed_control_system

    Computers had already been applied to process automation for some time in the form of both direct digital control (DDC) and setpoint control. In the early 1970s Taylor Instrument Company , (now part of ABB) developed the 1010 system, Foxboro the FOX1 system, Fisher Controls the DC 2 system and Bailey Controls the 1055 systems.

  3. SCADA - Wikipedia

    en.wikipedia.org/wiki/SCADA

    In smaller SCADA systems, the supervisory computer may be composed of a single PC, in which case the HMI is a part of this computer. In larger SCADA systems, the master station may include several HMIs hosted on client computers, multiple servers for data acquisition, distributed software applications, and disaster recovery sites.

    en.wikipedia.org/wiki/Direct_digital_control

    Most of the integration platforms are either a PC or a network appliance. In many cases, the HMI (human machine interface) or SCADA (Supervisory Control And Data Acquisition) are part of it. Integration platform examples, to name only a few, are the Tridium Niagara AX, Trend Controls, TAC Vista, CAN2GO and the Unified Architecture i.e. OPC ...

    en.wikipedia.org/wiki/Remote_Terminal_Unit

    A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

    This is a commonly-used architecture industrial control systems, however there are concerns about SCADA systems being vulnerable to cyberwarfare or cyberterrorism attacks. [6] The SCADA software operates on a supervisory level as control actions are performed automatically by RTUs or PLCs. SCADA control functions are usually restricted to basic ...

    IntegraXor is a supervisory control and data acquisition (SCADA) and human-machine interface (HMI) software system developed by Ecava and first released in 2003. [1] [2]

  9. Display Data Channel - Wikipedia

    en.wikipedia.org/wiki/Display_Data_Channel

    Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
