3 Definitions
For the purposes of this part of IEC 60092, the following definitions, having special application to the control, monitoring, alarm and protection equipment, apply. For definitions of general and more particular terms, reference is made to IEC 60050 (IEV) and other normative documents. 3.1 accuracy quality which characterizes the closeness of a measured value to the corresponding true value 3.2 alarm functions functions intended to alert relevant personnel, by visual and audible means, in the event of any condition requiring their attention 3.3 availability ability of an item to be in a state to perform a required function under given conditions at a given time interval, assuming that the required external resources are provided 3.4 centralized control control of all operations of a controlled system from one central control position 3.5 computer-based system system that consists of one or more programmable electronic devices with their connections, peripherals and software necessary to carry out automatically specified functions NOTE The following types of programmable devices could form part of a computer system: main-frame, mini- computer, micro-processor-based computer, programmable logic controller. 3.6 control functions functions intended to regulate the behavior of equipment or systems 3.7 control position (control station) group of control devices by which an operator can control the performance of a machine, apparatus, process or assembly of machines and apparatus. NOTE A control position will generally enable an operator to verify the achievement of the desired conditions by means of an appropriate monitoring system
