OT to IT Convergence – What’s all the Buzz About - Alben

  1. 1. Building management/Automation System (BAS): an electrical system controlling a facility’s heating, ventilation and air conditioning (HVAC) system. May also control lighting, fire safety and security systems, plumbing, elevators, etc.Generally architected as a DistributedControl System. DistributedControl System (DCS): a control system comprised of control elements distributed throughout a facility such as a refinery, power or manufacturing plant, mine, network of pipelines, or ship. Generally consists of a number of supervisory computers and one or more controlling computers in a hierarchical arrangement. It may also include coordinating computers between the supervisory and control levels. Historian: a software service within an industrial control system which accumulates timestamped sensor and event data in a database which can be queried or used to visualize trends in the Human-Machine Interface.The historian is a client that requests data from a data acquisition server. Human-Machine Interface (HMI): a computer enabling a human operator to monitor and interact with control systems and processes. It analyzes and presents data requested from sensors and data acquisition servers. IndustrialControl System (ICS): an umbrella term used to refer to multiple types of control systems, including DistributedControl Systems, BuildingAutomation Systems, Programmable Logic Controllers and Supervisory ControlAnd DataAcquisition systems. A similar term, Process Control Domain (PCD), is common in the Oil & Gas industries. Industrial Internet: the interconnected web of intelligent industrial products, services and processes that communicate with people and each other. Industrial Internet ofThings (IoT): the next evolutionary phase of OT, in which operational technology extends functions and capabilities through the Industrial Internet.This is an ongoing development.Operational Technology (OT): the hardware and software automation and control systems and components that monitor, measure, and protect infrastructure ranging from fleets of machines to power grids, refineries, and manufacturing and processing plants. It monitors and/or controls physical equipment and events. Process Control Network (PCN): a communication network providing communication of data and commands between monitoring, measuring and control components of a SCADA system. Programmable Logic Controller (PLC): a computer used to automate industrial equipment or processes. Largely applied to limited-purpose and hardened devices designed specifically to operate in industrial working environments. RemoteTerminalUnit (RTU): co-located with sensing equipment to collect and communicate data to supervisory systems in a SCADA network, as well as to receive supervisory commands and communicate to the connected equipment. Often have limited control capabilities. Safety Instrumented Systems (SIS): control systems specifically engineered to fail to a “safe” state to reduce the likelihood or prevent safety, health and environmental impacts. Supervisory ControlAnd DataAcquisition (SCADA): a system, which monitors, reports on and controls remote equipment. Generally consists of one or more supervisory and control computers, data acquisition computers, programmable logic controllers, remote terminal units, one or more historians, and a Process Control Network. IntelligentTransportation Solutions, (ITS) are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. Although ITS may refer to all modes of transport, EU Directive 2010/40/EU (7 July 2010) defined ITS as systems in which information and communication technologies are applied in the field of road transport, including infrastructure, vehicles and users, and in traffic management and mobility management, as well as for interfaces with other modes of transport.

  3. 3. CSX train signaling system: The Sobig computer virus was blamed for shutting down train signaling systems throughout the East Coast of the United States.The virus infected the computer system at CSX Corporation’s Jacksonville, Florida, headquarters, shutting down signaling, dispatching, and other systems.According to an Amtrak spokesman, 10Amtrak trains were affected.Train service was either shut down or delayed up to6 hours. Taum SaukWater Storage Dam failure:TheTaum Sauk Water Storage Dam, approximately100 miles south of St. Louis, Missouri, suffered a catastrophic failure, releasing a billion gallons of water. According to the dam’s operator, the incident may have occurred because the gauges at the dam read differently than the gauges at the dam’s remote monitoring station. Bellingham,Washington, gasoline pipeline failure: 237,000 gallons of gasoline leaked from a 16-inchpipelineand ignited an hour and a half later, causing three deaths, eight injuries, and extensive property damage.The pipeline failure was exacerbated by poorly performing control systems that limited the ability of the pipeline controllers to see and react to the situation.
  4. 4. DNP3 (Distributed Network Protocol) is a set of communications protocols used between components in process automation systems, mainly used in public utilities such as electric and water agencies. It was developed for communications between various types of data acquisition and control equipment. It plays a crucial role in SCADA systems, where it is used by SCADA Master Stations (a.k.a. Control Centers), Remote terminal Unites (RTUs) and Intelligent Electronic Devices (IEDs). It is primarily used for communications between a master station and RTUs or IEDs. ICCP, the Inter-Control Center Communications Protocol (a part of IEC 60870-6), is used for inter-master station communications.
