A program including configuration data, symbols, and documentation.
Automates industrial processes (also known as programmable logic controller or programmable controller).
(electronic industries alliance rack) A standardized (EIA 310-D, IEC 60297, and DIN 41494 SC48D) system for mounting various electronic modules in a stack or rack that is 19 inches (482.6 mm) wide.
EN identifies one of many European standards maintained by CEN (European Committee for Standardization), CENELEC (European Committee for Electrotechnical Standardization), or ETSI (European Telecommunications Standards Institute).
An electronic communication bus between expansion I/O modules and a controller or bus coupler.
A connector to attach expansion I/O modules.
Rectangular connector for electrical signals with frequencies below 3 MHz, complying with IEC 60807-2.
(input/output)
(international electrotechnical commission) A non-profit and non-governmental international standards organization that prepares and publishes international standards for electrical, electronic, and related technologies.
(ingress protection) The protection classification according to IEC 60529 offered by an enclosure, shown by the letter IP and 2 digits. The first digit indicates 2 factors: helping protect persons and for equipment. The second digit indicates helping protect against water. IP 20 devices help protect against electric contact of objects larger than 12.5 mm, but not against water.
(national electrical manufacturers association) The standard for the performance of various classes of electrical enclosures. The NEMA standards cover corrosion resistance, ability to help protect from rain, submersion, and so on. For IEC member countries, the IEC 60529 standard classifies the ingress protection rating for enclosures.
The component of an application that consists of compiled source code capable of being installed in the memory of a logic controller.
A standard type of 8-pin connector for network cables defined for Ethernet.
(terminal block) The component that mounts in an electronic module and provides electrical connections between the controller and the field devices.
