Terms and abbreviations

Description

Term

Classification of the safety-related parts of a control system in respect of their resistance
to faults and their subsequent behavior in the fault condition, and which is achieved
by the structural arrangement of the parts, fault detection and/or by their reliability.
The categories are: B, 1, 2, 3 and 4. (EN ISO 13849-1)

Cat.

Common cause failure (%) (EN ISO 13849-1)

CCF

Control board built in a housing (often rail-mountable)

Control unit

Diagnostic coverage (EN ISO 13849-1)

DC

Digital input

DI

Digital input interlock

DIIL

Frequency converter for controlling AC motors

Drive

Emergency stop

E-stop

Physical size of the drive or power module

Frame, frame size

Hardware fault tolerance (IEC 61508)

HFT

Inverter module(s) under control of one control unit, and related components. One
inverter unit typically controls one motor.

Inverter unit

Average probability of dangerous failure on demand (IEC 61508)

PFD

avg

Average frequency of dangerous failures per hour (IEC 61508)

PFH

Performance level. Levels a...e correspond to SIL (EN ISO 13849-1)

PL

Periodic test performed to detect failures in a safety-related system so that, if neces-
sary, a repair can restore the system to an “as new” condition or as close as practical
to this condition. (IEC 61508, IEC 62061)

Proof test

Systematic capability (IEC 61508)

SC

Safety integrity level (1...3) (IEC 61508)

SIL

Maximum SIL (level 1...3) that can be claimed for a safety function or subsystem
(IEC/EN 62061)

SILCL

Safe torque off (IEC/EN 61800-5-2)

STO

There are three categories of stop functions defined by IEC/EN 60204-1:

•stop category 0: an uncontrolled stop where power to the machine actuators is re-

moved immediately (for example, STO)

•stop category 1: a controlled stop where the machine actuators have power for

stopping, after which the power is removed (SS1)

•stop category 2: a controlled stop where the machine actuators continue to have

power (SS2).

Stop category

Supply module(s) under control of one control unit, and related components.

Supply unit

Proof test interval. Defines the probabilistic failure rate (PFH or PFD

avg

) for the safety

function or subsystem. Performing a proof test at a maximum interval of T

1

is required

to keep the SIL capability valid. The same interval must be followed to keep the PL
capability (EN ISO 13849) valid. Note that any T

1

values given cannot be regarded

as a guarantee or warranty.
