3.1

part

physical entity with its digital description [ data (3.19) ] that is transported into and out of the machine (3.4) by the machine tending system (3.3)

3.2

functional unit

device or system which transports, receives or renders parts (3.1)

3.3

machine tending system

functional unit (3.2) transporting parts (3.1) without changing their physical properties

Note 1 to entry: See Figure A.1.

3.4

machine

functional unit (3.2) changing the physical properties of parts (3.1)

Note 1 to entry: See Figure A.1.

3.5

automated machine tending

process of transporting parts (3.1) into or out of a machine (3.4) by a machine tending system (3.3)

Note 1 to entry: See Figure A.1.

3.6

interface

shared boundary between two functional units (3.2) , defined by various characteristics pertaining to the functions, physical interconnections, signal (3.7) exchanges, and other characteristics, as appropriate

[SOURCE: ISO/IEC 2382:2015, 2121308, modified — Notes to entry have been removed.]

3.7

signal

information transferred between functional units (3.2) via the interface (3.6)

3.8

interference area

shared work area between functional units (3.2)

Note 1 to entry: See Figure A.2.

3.9

interference area preposition

interference area (3.8) without the area of the transfer station (device)

Note 1 to entry: See Figure A.2.

3.10

coherent transfer

transfer of parts (3.1) where one functional unit (3.2) keeps the part form-locked until the other functional unit has it securely clamped

Note 1 to entry: A distinction between coherent and non-coherent transfer can be made for loading and unloading operations.

3.11

function mode

status of a functional unit (3.2) indicating if signals (3.7) are valid/executed

3.12

conformance class

predefined subset of signals (3.7) selected to achieve a specified set of functions, for which conformance can be claimed

Note 1 to entry: Predefined sets of functions are conformance class 1"Minimum set of signals", conformance class 2"Extended scope" and conformance class 3"Extended scope with process optimization".

3.13

conformance option

predefined subset of signals (3.7) that can be selected to add a set of functions to a conformance class (3.12) , for which conformance can be claimed

3.14

loading access

interlocking guard which separates the machine (3.4) from the machine tending system (3.3) for exchanging parts (3.1)

Note 1 to entry: See Figures A.3 and A.4.

3.15

PFHD value

probability of a dangerours failure per hour

3.16

pulse 1 Hz

signal (3.7) of the format boolean alternating in an interval of 0,5s

3.17

handshake

interaction between functional units (3.2) with a request as trigger and an acknowledge or state (3.18) signal (3.7) as answer

3.18

state

signal (3.7) describing a condition

3.19

data

signal (3.7) containing information relevant to a part (3.1)

3.20

interlinked operation

intdOp

function mode (3.11) indicating that a functional unit (3.2) participates in the automated machine tending (3.5)

3.21

single operation

SOp

function mode (3.11) indicating that a functional unit (3.2) is processing/handling a part (3.1) but is not in interlinked operation (3.20)

3.22

single step

SSp

function mode (3.11) indicating that a functional unit (3.2) is traversed in sequential movements where each movement is initiated by an operator

3.23

setup operation

SetOp

function mode (3.11) indicating that an operator can manually execute any movement of a functional unit (3.2)
