Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 23570-1 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and
integration, Subcommittee SC 1, Physical device control.
ISO 23570 consists of the following parts, under the general title Industrial automation systems and
integration — Distributed installation in industrial applications:
⎯ Part 1: Sensors and actuators
⎯ Part 2: Hybrid communication bus
⎯ Part 3: Power distribution bus

Introduction
Modern machine tools for the discrete parts manufacturing industry are complex systems, consisting of
subsystems for material preparation (metal removal, material forming, etc.), material handling, fixturing and
transfer lines for moving parts from one station to another. Each subsystem, in turn, is itself a complex system,
including many sensors, actuators and control elements that receive and transmit electric signals and/or
require electric power. To reduce down time in case of failure, most of them use cable assemblies for quick
replacement. Proper operation of the system as a whole requires co-ordination of the subsystems, which
requires more cables and connectors. As a consequence of this complexity, a large variety of cables and
connectors is required for the proper operation of such a machine tool. The increasing number of sensors,
actuators and control elements leads to an increasing variety of such cable assemblies. This variety results in
increased maintenance costs, due to complexity, large spare parts inventory and increased training costs for
maintenance personnel.

ISO 23570-1:2005(E)
ISO 23570 prescribes a set of requirements for cables, connectors and parameter selections within these
elements, which, if implemented completely, will greatly reduce the wiring complexity and maintenance cost of
such machine systems. Benefits will occur to the manufacturer of such systems in the form of decreased
complexity costs and to the user of such systems in the form of decreased down time because of decreased
parts inventory and simplified maintenance training.
The technology described in ISO 23570 may have applicability to other industries and processes; there is no
intention of restricting it to discrete parts manufacturing.
There are three main areas addressed within ISO 23570:
⎯ the interconnection of sensors and actuators to the system backbone;
⎯ a hybrid system backbone containing an information path (a fieldbus) and a source of power to the field
devices;
⎯ a power trunk capable of providing power to all the auxiliary motors in the system.
Large power devices, such as spindle motors for metal removal, are not covered by ISO 23570.
Machine tools described in ISO 23570 are subject to constraints imposed by national and international safety
standards. It is the intent of ISO 23570 to specify system elements that support the compliance with such
standards.
In Figure 1, the solid cable represents the power distribution bus providing three-phase a.c. power for electric
motors. The open cable represents a hybrid communication bus, containing both a fieldbus communication
channel and low voltage power.
The centre of Figure 1 shows (3) a control cabinet serving three sets of distribution buses. This box contains
the fieldbus communication front end, the low voltage power supplies and the three-phase power supplies.
To the left of the control cabinet are (1) a motor with integrated electronics and (2) a fixed speed motor with a
separate motor controller. Both units are linked to the control cabinet by both the communication bus and the
power distribution bus.
To the right of the control cabinet are (4) a fixed speed motor with an attached motor controller, (5) a variable
speed motor with an integrated I/O module connected to several sensors and actuators, and (6) another I/O
module connected to several sensors and actuators, including a hydraulic/pneumatic valve. The I/O module
(6) is linked to the control cabinet only by the hybrid communication bus.
In front of the control cabinet are three more units, (7) a motor with integrated electronics, (8) another I/O
module connected to several sensors and actuators including a hydraulic/pneumatic valve, and (9) a remote
control terminal.
Figure 1 is intended to illustrate the variety of interconnections possible using the elements of ISO 23570.
This part of ISO 23570 provides the requirements for sensors, actuators and I/O modules that support this
system requirement. ISO 23570-2 provides the requirements for a shared communication and low voltage
power distribution system. ISO 23570-3 provides the requirements for distribution of power to the low power
motor systems.
While significant reduction in maintenance and operational costs may be achieved by adoption of individual
parts of ISO 23570, the greatest benefit will occur only if all parts are implemented.
This part of ISO 23570 provides the requirements for sensors, actuators and I/O modules that support this
system requirement.
