IEC 62745:2017 pdf download.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 1 21 00.

3 Terms, definitions and abbreviations
For the purposes of this document, the following terms and definitions apply. For an alphabetical list of definitions, see Table 1 . For list of abbreviations see Table 2.3.1 cableless control transmission of the machine operator’s commands without any wired connection 3.2 cableless control system CCS system consisting of at least one remote station and one base station, which uses cableless control to transmit commands between them 3.3 receiver part of a cableless control system which receives frames from a transmitter 3.4 transmitter part of a cableless control system which sends frames to a receiver 3.5 operator control station assembly of one or more control actuators (part of a device to which an external manual action is to be applied) fixed on the same panel or located in the same enclosure Note 1 to entry: An operator control station can also contain related equipment, for example, potentiometers, signal lamps, instruments, display devices, etc. 3.6 frame “package” of information exchanged between a remote station and a base station, and consisting of, for example: a) address code; b) operating commands; c) error detection code; d) other commands, signals or information Note 1 to entry: A “frame” is sometimes referred to as a “telegram” or “message”. 3.7 address code part of a frame that enables a base station or a remote station to recognise frames that are intended to convey commands to it Note 1 to entry: The base station or remote station respond to commands that are recognised as having the relevant address code. 3.8 operating command signal control signal that is intended to initiate, modify or maintain a machine function 3.9 error detection code additional information added to each frame to enable the detection of transmission errors 3.1 0 neutral frame frame in which all operating command signals are in a state such that when it is received at the base station it does not activate any outputs intended for control of hazardous operations of the machine
