SCADA is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes. It also covers sensors and other devices, such as programmable logic controllers, which interface with process plant or machinery.
A fieldbus is a member of a family of industrial digital communication networks used for real-time distributed control. Fieldbus profiles are standardized by the International Electrotechnical Commission (IEC) as IEC 61784/61158.
In electrical engineering and power system automation, the International Electrotechnical Commission 60870 standards define systems used for telecontrol. Such systems are used for controlling electric power transmission grids and other geographically widespread control systems. By use of standardized protocols, equipment from many different suppliers can be made to interoperate. IEC standard 60870 has six parts, defining general information related to the standard, operating conditions, electrical interfaces, performance requirements, and data transmission protocols. The 60870 standards are developed by IEC Technical Committee 57.
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations. It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. The abstract data models defined in IEC 61850 can be mapped to a number of protocols. Current mappings in the standard are to Manufacturing Message Specification (MMS), GOOSE [see section 3, Terms and definitions, term 3.65 on page 14], SV or SMV, and soon to web services. In the previous version of the standard, GOOSE stood for "Generic Object Oriented Substation Event", but this old definition is still very common in IEC 61850 documentation. These protocols can run over TCP/IP networks or substation LANs using high speed switched Ethernet to obtain the necessary response times below four milliseconds for protective relaying.
Profinet is an industry technical standard for data communication over Industrial Ethernet, designed for collecting data from, and controlling equipment in industrial systems, with a particular strength in delivering data under tight time constraints. The standard is maintained and supported by Profibus and Profinet International, an umbrella organization headquartered in Karlsruhe, Germany.
Instruction list (IL) is one of the 5 languages supported by the initial versions of IEC 61131-3 standard, and subsequently deprecated in the third edition.
The international standard IEC 61499, addressing the topic of function blocks for industrial process measurement and control systems, was initially published by the International Electrotechnical Commission (IEC) in 2005. The specification of IEC 61499 defines a generic model for distributed control systems and is based on the IEC 61131 standard. The concepts of IEC 61499 are also explained by Lewis and Zoitl as well as Vyatkin.
IEC 61508 is an international standard published by the International Electrotechnical Commission (IEC) consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems. It is titled Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems.
An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections. Control systems receive data from remote sensors measuring process variables (PVs), compare the collected data with desired setpoints (SPs), and derive command functions that are used to control a process through the final control elements (FCEs), such as control valves.
Profisafe is a standard for a communication protocol for the transmission of safety-relevant data in automation applications with functional safety. This standard was developed jointly by several automation device manufacturers in order to be able to meet the requirements of the legislator and the IFA for safe systems. The required safe function of the protocol has been tested and confirmed by TÜV Süd. The PROFIBUS Nutzerorganisation e.V. in Karlsruhe supervises the standardization for the partner companies and organizes the promotion of this common interface.
IEC 60870 part 6 in electrical engineering and power system automation, is one of the IEC 60870 set of standards which define systems used for telecontrol in electrical engineering and power system automation applications. The IEC Technical Committee 57 have developed part 6 to provide a communication profile for sending basic telecontrol messages between two systems which is compatible with ISO standards and ITU-T recommendations.
The IEC 61970 series of standards by the International Electrotechnical Commission (IEC) deals with the application program interfaces for energy management systems (EMS). The series provides a set of guidelines and standards to facilitate:
Orchestra Control Engine is a suite of software components used for the planning, development and deployment of real-time control applications for industrial machines and robots.
Codesys is an integrated development environment for programming controller applications according to the international industrial standard IEC 61131-3.
IEC 61968 is a series of standards under development that will define standards for information exchanges between electrical distribution systems. These standards are being developed by Working Group 14 of Technical Committee 57 of the International Electrotechnical Commission. IEC 61968 is intended to support the inter-application integration of a utility enterprise that needs to collect data from different applications that are legacy or new and each has different interfaces and run-time environments. IEC 61968 defines interfaces for all the major elements of an interface architecture for distribution management systems (DMS) and is intended to be implemented with middleware services that broker messages among applications.
IEC 62443 is an international series of standards that address cybersecurity for operational technology in automation and control systems. The standard is divided into different sections and describes both technical and process-related aspects of automation and control systems cybersecurity.
PLCopen is an independent organisation providing efficiency in industrial automation based on the needs of users. PLCopen members have concentrated on technical specifications around IEC 61131-3, creating specifications and implementations in order to reduce cost in industrial engineering. The outcome for example is standardized libraries for different application fields, harmonized language conformity levels and engineering interfaces for exchange. Experts of the PLCopen members are organized in technical committees and together with end users define such open standards.
Agile Automation refers to the application of select Agile software development principles, patterns and practices, to the area of industrial automation and process control software development. The term was coined by HAL Software (Ireland) in 2013.
IO-Link is a short distance, bi-directional, digital, point-to-point, wired, industrial communications networking standard used for connecting digital sensors and actuators to either a type of industrial fieldbus or a type of industrial Ethernet. Its objective is to provide a technological platform that enables the development and use of sensors and actuators that can produce and consume enriched sets of data that in turn can be used for economically optimizing industrial automated processes and operations. The technology standard is managed by the industry association Profibus and Profinet International.
