SAFETY OF MACHINERY – REQUIREMENTS FOR
CABLELESS CONTROL SYSTEMS OF MACHINERY

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62745 has been prepared by IEC technical committee 44: Safety
of machinery – Electrotechnical aspects.
The text of this standard is based on the following documents:

INTRODUCTION
Cableless control systems (CCS) are increasingly being used to provide an operator interface
on a wide range of machinery. The functionality of a CCS and the way in which it interfaces
with the overall machine control system can therefore affect the safety of the machinery.
IEC 62745 specifies requirements for the functionality of a CCS that is interfaced with or is
part of a machine control system for use as an operator control station on a machine.
The extent to which the functionality of a CCS is relied upon to minimise risk on a machine is
a key selection criterion. It is therefore important to select a CCS that provides suitable
control functions with an appropriate safety integrity in accordance with the risk assessment
at the machine.
In some particular applications, the requirements for a CCS can exceed those specified in this
document.

SAFETY OF MACHINERY – REQUIREMENTS FOR
CABLELESS CONTROL SYSTEMS OF MACHINERY



1 Scope
This standard specifies requirements for the functionality and interfacing of cableless (for
example, radio, infra-red) control systems that provide communication between operator
control station(s) and the control system of a machine. Specific requirements are included for
such operator control stations that are portable by the operator.
NOTE The part of the cableless control system that is used as an operator control station is sometimes referred
to as the ‘transmitter’ and the part that interfaces with the machine control system is sometimes referred to as the
‘receiver’. However, to take account of the possibility of bi-directional communication, this standard refers to these
individual parts as the ‘remote station’ and the ‘base station’ respectively.
This document does not deal with cableless communication between parts of a machine(s)
that are not operator control stations.
This document is not intended to specify all of the requirements that are necessary for the
design and construction of a cableless control system. For example, it does not specify
communication protocols, frequency or bandwidth aspects, nor the full range of constructional
requirements such as impact resistance, ingress protection, electromagnetic compatibility,
etc.
The provisions of this document are intended to be applied in addition to the requirements for
electrical equipment in the IEC 60204-1.
This document is a type-B2 standard as stated in ISO 12100.

Note 1 to entry: An operator control station can also contain related equipment, for example, potentiometers,
signal lamps, instruments, display devices, etc.
3.6

---------------------- Page: 15 ----------------------

SIST EN 62745:2017
– 10 – IEC 62745:2017 © IEC 2017
Note 1 to entry: Neutral frames can be used to maintain communication (i.e. a valid signal) between a transmitter

initiate a stop function
Note 1 to entry: Stop outputs can be safety-related or non-safety-related. See also Table 3.
Note 2 to entry: Interfaces to field bus part of a CCS base station can also be considered as an output circuit.
