3.1

auxiliary input unit

autonomous control function (CF) providing Auxiliary Controls for common use that can also be physically located within an electronic control unit (ECU), or on the virtual terminal (VT)

3.2

object pool

collection of objects that completely define the operator interface for an implement or a single Working Set

Note 1 to entry: The complete VT definition will be made up of one or more object pools — one for each Working Set.

3.3

Object ID

numeric value which identifies a specific object within an object pool

Note 1 to entry: Object ID values range from 0 to FFFF₁₆ (65535₁₀), with 65535 as the NULL Object ID.

3.4

attribute ID

AID

numeric value which references a specific object's attribute

Note 1 to entry: AID values range from 0 to FF₁₆ (255₁₀), with 255 as the NULL_AID.

3.5

char

single character where the size is 1 byte

Note 1 to entry: Commonly used for ISO 8859 characters (e.g. 41₁₆ in ISO 8859-1 represents “A”) (see Annex K).

3.6

character

single text grapheme or symbol, as in an alphabet

Note 1 to entry: Size is variable based on the encoding scheme [see char (3.5) and WideChar (3.11) ].

3.7

code plane

group of 65536 possible character codes

Note 1 to entry: Unicode/ISO 10464 organizes the characters in 17 code planes numbered 0 to 16.

3.8

open input object

state of an input object where the object has focus and it is open for operator input

Note 1 to entry: Open input object is used interchangeably with data input.

3.9

selected input object

state of an input object where the object has focus but it is not open for operator input

Note 1 to entry: Selected input object is used interchangeably with “has focus”.

3.10

surrogate pair

32 bit code for characters composed of a 16 bit high pair and a 16 bit low pair

Note 1 to entry: UTF-16 encoding of characters in code plane 1 to 16 (see 4.6.19.7).

Note 2 to entry: UTF-16 Character encoding scheme defined by ISO 10646.

3.11

WideChar

single character with a size of 2 bytes encoded in little endian order

Note 1 to entry: Two WideChars can be combined to indicate character codes exceeding 16-bit (see 4.6.19.7).

3.12

WideString

zero or more characters composed of the primitive type “WideChar” always preceded by the byte order mark FEFF₁₆

3.13

8-bit string

zero or more characters composed of the primitive type “char”

Note 1 to entry: String length is variable.

3.14

VT Number

number that is used to uniquely identify each connected VT to the operator

Note 1 to entry: See 4.6.25 and D.18.

3.15

User-Layout Data Mask

special Data Masks that are controlled by the VT but laid out by the operator

Note 1 to entry: See 4.1 for information on data mask variations, and 4.7 for User-Layout Data Mask information.

3.16

Window Cell

rectangular presentation cell in a grid on a User-Layout Data Mask

Note 1 to entry: See 4.7.

3.17

Window Mask object

rectangular presentation area composed of one or more adjacent Window Cells

Note 1 to entry: See 4.7.

3.18

User-Layout Soft Key Mask

Soft Key Masks that are controlled by the VT but laid out by the operator

Note 1 to entry: See 4.7.

3.19

Key Cell

cell that is the size of a Soft Key designator in a User-Layout Key Mask

Note 1 to entry: See 4.7.

3.20

Key Group object

area of one or more Key Cells and contains a grouping of one or more Key objects

Note 1 to entry: See 4.7.

3.21

Non-VT Screen

display screen that is not part of the VT application or one in which the layout is controlled by the VT

3.22

Non-VT Area

visible area outside the normal Data Mask and Soft Key Mask areas

3.23

referenced WS

working set with an object pool containing objects which are shown by another object pool via the External Object Pointer object

Note 1 to entry: See 4.6.11.6.

3.24

referencing WS

working set with an object pool which shows object(s) from another object pool via the External Object Pointer object

Note 1 to entry: See 4.6.11.6.

3.25

Working Set(s) with a NAME that exactly matches other Working Sets, when the Self Configurable, Instance fields, and Identity Number are excluded in the comparison

3.26

Line End

“cursor” or text positioning control intended to locate the following displayable character “font height” pixels downward and at the left-most position in the containing object

Note 1 to entry: See 4.6.19.6.

3.27

Model Identification Code

proprietary code defined by the manufacturer that defines a unique model and version of an Auxiliary Input Unit that does not change at runtime, and is revised by the manufacturer when a new and incompatible Auxiliary Input Unit is created
