The work of preparing International Standards is normally carried out through IS

8、O 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 c

9、losely 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. D

10、raft 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 do

13、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

14、 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 requir

15、es 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 incre

16、asing 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.

19、hin 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 dow

20、n 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 23

21、570: 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

22、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

23、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 thre

24、e 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 u

25、nits 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,

26、 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)

27、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 se

28、nsors, 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 reducti

29、on 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. INTER

31、ne tools and similar large pieces of industrial automation. This specification includes cable types, sizes and sheath colours, connector types and contact assignments, and diagnostic functions appropriate to the sensors and actuators. This part of ISO 23570 specifies the interconnection of sensors a

32、nd actuators with I/O modules that use their input or direct their output, and the diagnostic functions appropriate to those sensors and actuators. This part of ISO 23570 does not address operation of such equipment with respect to safety issues. Appropriate safety standards should be consulted for

33、such requirements. 2 Conformance Producers of sensors, actuators, cable assemblies and I/O modules may claim conformance to this part of ISO 23570 if they meet the requirements of Clause 5. Producers of discrete part manufacturing equipment may claim conformance to this part of ISO 23570 if all the

34、components of the discrete part manufacturing equipment that are subject to the requirements of Clause 5 meet those requirements. 3 Normative references The following referenced documents are indispensable for the application of this document.
