According to the IEC standard, % is a prefix that identifies internal memory addresses in the logic controller to store the value of program variables, constants, I/O, and so on.
(Canadian standards association) The Canadian standard for industrial electronic equipment in hazardous environments.
(Deutsches Institut für Normung) A German institution that sets engineering and dimensional standards.
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).
A device for length or angular measurement (linear or rotary encoders).
A part of a machine including sub-assemblies such as conveyors, turntables, and so on.
FAST input/output Specific I/O modules with some electrical features (for example, response time) while the treatment of these channels are done directly by the controller
(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.
(ingress protection) The protection classification according to IEC 60529. IP 67 modules are protected against ingress of dust, contact, and water up to an immersion depth of 1 m.
(millisecond)
A system of interconnected devices that share a common data path and protocol for communications.
(serial real-time communications system) A digital control bus that interconnects, motion controls, drives, I/Os, sensors, and actuators for numerically controlled machines and systems. It is a standardized and open controller-to-intelligent digital device interface, designed for high-speed serial communication of standardized closed-loop real-time data.
(terminal block) The component that mounts in an electronic module and provides electrical connections between the controller and the field devices.
(underwriters laboratories) A US organization for product testing and safety certification.
