purposeful action to affect an intended change in the system or equipment

3.8

individual whose primary duties relate to the conduct of monitoring and control functions, usually at a control workstation, either on their own or in conjunction with other personnel both within the control room or outside

[SOURCE: ISO 11064-3]

3.11

control workstation

single or multiple working position, including all equipment such as computers and communication terminals and furniture at which control and monitoring functions are conducted

raw material from which a user extracts information

Note 1 to entry: “Data” can include numbers, words and/or pictures, such as a view out of a window.

3.13

digital display

display in which the information is shown in numerical code

[SOURCE: EN 894-2]

3.14

display

device for presenting information that can change with the aim of making things visible, audible or discriminable by tactile or proprioceptive perception

[SOURCE: ISO 11064-3]

Note 1 to entry: See also Figure 1.

3.15

element

basic component used to make up formats such as abbreviations, labels, items, symbols, coding and highlighting

Note 1 to entry: Based on NUREG-0700 ^[14] .

Note 2 to entry: See also Figure 1.

3.16

event

any spontaneous transition from one discrete status to another

Note 1 to entry: If the initial status is not displayed (i.e. it is normal), an event will be perceived as the occurrence of a defined change of status. (“Occurrence” is here synonymous with a transition from one discrete status to another and “status” can relate to either normal or abnormal conditions.)

3.17

format

pictorial display of information on visual display units (VDU) such as message text, digital presentation, symbols, mimics, bar chart, trend graphics, pointers, multi-angular presentation

[SOURCE: IEC 60964]

Note 1 to entry: For the purposes of ISO 11064, this term also covers auditory displays.

3.18

human-system interface

HIS

human-machine interface

HMI

all matters and procedures of a machine (or system) available for interaction with its (human) users

3.19

information

anything which is not known by a person in advance

Note 1 to entry: Information is extracted from data (3.12) .

Note 2 to entry:Knowledge is required to interpret information.

Note 3 to entry: One example of another definition of information is “commodity that reduces the uncertainty”. The definition used for the purposes of this part of ISO 11064 is essential for allocating the appropriate importance or quality value to display elements.

3.20

interaction

dialogue

exchange of information between a user and a system via the human-system interface to achieve the intended goal

3.21

mimic

mimic display

mimic diagram

simplified graphical depiction of a system by presenting its components and their interrelationships

3.22

monitoring

activity for the purpose of detecting deviations from normal operation (by checking variables, or their course against limits, trends or the values of other variables) to enable timely and appropriate action for response

Note 1 to entry: Monitoring of the process is performed either by a human being and/or by a control system.

3.23

overview display

high-level abstraction, or low level of detail, of the system status, covering the areas of responsibility

Note 1 to entry: An overview display supports control room personnel in obtaining an overall view of systems status by bringing to their attention significant changes in system conditions and presenting those that are important.

3.24

page

defined set of information that is intended to be displayed on a single display screen

Note 1 to entry: Based on NUREG-0700 ^[14] .

Note 2 to entry: A window may form an entire page where it fills a single display screen. See Figure 1.

3.25

process control

monitoring and manipulation of variables influencing the behaviour of a process to conform to specified objectives

Note 1 to entry: Operators use displays and controls in executing their activities of monitoring, control, and system management.

Note 2 to entry: Process control is accomplished by regulation or manipulation of variables influencing the conduct of a process in such a way as to obtain a product of desired quality and quantity in an efficient manner ^[15] .

3.26

status

state

distinct condition of an object

Note 1 to entry: The object can be a system, a process unit, a machine, etc. Conditions can be operation modes — either normal (e.g. “on”, “closed”, “standby”) or abnormal (e.g. “disturbed”). They may be determined by checking values of variables against limits (e.g. “too high” or “high alarm”).

3.27

symbol

letters, digits, pictorial representations or combinations of these, used for labelling a display's graduations, or as a means of identifying the display itself

3.28

task

human activities required to achieve a goal

Note 1 to entry: Adapted from ISO 9241-11:1998, definition 3.9.

Note 2 to entry: The task is accomplished by means of (several) jobs. The goal is specified by the organization responsible for the human-machine system.

3.29

visual display

display (in the sense of format) providing visual presentation of data, mappings or videos

Note 1 to entry: Visual displays are classified in accordance with the presentation mode of single data (analogue, binary, digital, hybrid) of a single datum. Complex data can be presented in graphic or alphanumeric dimension (2D, 3D) providing a relation between time of view and time presented (“predictive” or “quickened” display).

3.30

window

independently controllable area on the display screen used to present objects and/or conduct a dialogue with a user
