A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. Dick Morley is considered as the father of PLC as he had invented the first PLC, the Modicon 084, for General Motors in 1968.
Instrumentation is a collective term for measuring instruments, used for indicating, measuring and recording physical quantities. It is also a field of study about the art and science about making measurement instruments, involving the related areas of metrology, automation, and control theory. The term has its origins in the art and science of scientific instrument-making.
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines. The control systems are designed via control engineering process.
HVAC equipment needs a control system to regulate the operation of a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state with a target state. Then the control system draws a conclusion what action has to be taken.
Allgemeine Elektricitäts-Gesellschaft AG was a German producer of electrical equipment. It was founded in 1883 by Emil Rathenau as the Deutsche Edison-Gesellschaft für angewandte Elektricität in Berlin.
KUKA is a German manufacturer of industrial robots and factory automation systems owned by Chinese appliance manufacturer Midea Group.
The EnOcean technology is an energy harvesting wireless technology used primarily in building automation systems, but also in other application fields such as industry, transportation, logistics or smart homes solutions. The energy harvesting wireless modules are manufactured and marketed by the company EnOcean, headquartered in Oberhaching near Munich. The modules combine micro energy converters with ultra low power electronics and wireless communications and enable batteryless, wireless sensors, switches, and controls.
A process automation or automation system (PAS) is used to automatically control a process such as chemical, oil refineries, paper and pulp factories. The PAS often uses a network to interconnect sensors, controllers, operator terminals and actuators. A PAS is often based on open standards in contrast to a DCS, which is traditionally proprietary. However in recent times the PAS is considered to be more associated with SCADA systems.
Building automation(BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems, and other interrelated systems. Some objectives of building automation are improved occupant comfort, efficient operation of building systems, reduction in energy consumption, reduced operating and maintaining costs and increased security.
Direct digital control is the automated control of a condition or process by a digital device (computer). Direct digital control takes a centralized network-oriented approach. All instrumentation is gathered by various analog and digital converters which use the network to transport these signals to the central controller. The centralized computer then follows all of its production rules and causes actions to be sent via the same network to valves, actuators, and other heating, ventilating, and air conditioning components that can be adjusted.
The PACE Award is an annual award from Automotive News. The focus of the award is an innovation (i) developed primarily by a supplier, (ii) that is new to the automotive industry, (iii) that is in use, and (iv) that "changes the rules of the game". Awards have been given for products, materials, processes, capital equipment, software and services. A panel of independent judges from industry, finance, research, and academia choose finalists from the initial applicants, make site visits to evaluate the innovation, and then gather to select winners, independent of the sponsors. Winners to date include suppliers from Japan, Korea, China, the US, Canada, Brazil, Germany, France, Italy, Poland and other European countries. Among the most awarded companies over the years are BorgWarner, Delphi Automotive, Federal-Mogul, Valeo and PPG Industries as well as Robert Bosch GmbH, Gentex Corporation, and Siemens.
NeSSI is a global and open initiative sponsored by the Center for Process Analysis and Control (CPAC) at the University of Washington, in Seattle.
OpenTherm (OT) is a standard communications protocol used in central heating systems for the communication between a central heating boiler and a thermostatic controller. As a standard, OpenTherm is independent of any single manufacturer. A controller from manufacturer A can in principle be used to control a boiler from manufacturer B. However, OpenTherm controllers and boilers do not always work properly together. The OpenTherm standard comprises a number of optional features and some devices may include manufacturer-specific features. The presence or absence of such features may impair compatibility with other OpenTherm devices.
Maxon Group is a Swiss manufacturer and supplier of high-precision motor systems. The group, including its subsidiaries, offers electric AC motors, DC motors, encoders, gears, motor controllers, and sensors.
Instrumentation is used to monitor and control the process plant in the oil, gas and petrochemical industries. Instrumentation ensures that the plant operates within defined parameters to produce materials of consistent quality and within the required specifications. It also ensures that the plant is operated safely and acts to correct out of tolerance operation and to automatically shut down the plant to prevent hazardous conditions from occurring. Instrumentation comprises sensor elements, signal transmitters, controllers, indicators and alarms, actuated valves, logic circuits and operator interfaces.
KMC Controls has designed and manufactured HVAC control system products and building automation systems since 1969. KMC was one of the early privately held controls manufacturer with a full line of digital, electronic, and pneumatic products in the United States. The latest products include BACnet digital controllers and thermostats.
KSB SE & Co. KGaA is a German multinational manufacturer of pumps, valves with headquarters in Frankenthal (Pfalz), Germany. The KSB Group has manufacturing plants, sales and marketing organizations, and service operations on every continent.
HomeSeer Technologies LLC is a technology company based in Bedford, New Hampshire, in the United States. HomeSeer makes home automation controllers and software, designed to integrate lighting, HVAC, security, AV and other subsystems in most homes. Additionally, the company maintains an online store of compatible home automation products and a free online community forum for users and dealers.
Eve Systems GmbH is a German smart home and home automation producer founded on June 27, 2018.
