1 Scope
Add, after the third paragraph, the following new paragraph:
While a data interface can be used to control optional safety-related ESPE functions
(Annex A), this standard does not provide specific requirements. Requirements for these
safety-related functions can be determined by consulting other standards (for example, IEC
61508, IEC/TS 62046, IEC 62061, and ISO13849-1).
2 Normative references
Add, to the existing list, the title of the following standard:
IEC 62061, Safety of machinery – Functional safety of safety-related electrical, electronic and
programmable electronic control systems
Page 15
3 Terms and definitions
Replace definition 3.5 by the following new definition:
61496-1 Amend. 1 © IEC:2007 – 3 –
3.5
electro-sensitive protective equipment
ESPE
assembly of devices and/or components working together for protective tripping or presence-
sensing purposes and comprising as a minimum
– a sensing device;
– controlling/monitoring devices;
– output signal switching devices and/or a safety-related data interface
NOTE 1 The safety-related control system associated with the ESPE, or the ESPE itself, may further include a
secondary switching device, muting functions, stopping performance monitor, etc. (see Annex A).
NOTE 2 A safety-related communication interface can be integrated in the same enclosure as the ESPE.
3.16
muting
temporary automatic suspension of a safety function(s) by safety-related parts of the control
system
NOTE For ESPE-muting, see Clause A.7.
Replace, on page 19, definitions 3.17 and 3.18 by the following new definitions:
3.17
OFF-state
state of the output(s) of the ESPE in which the machine under control is caused to stop
running and is prevented from starting (for example, the output circuit is interrupted and
disables the flow of current)
3.18
ON-state
state of the output(s) of the ESPE in which the machine under control is allowed to run (for
example, the output circuit is complete and enables the flow of current)
3.21
response time
Add, after the text of definition 3.21, the following new notes:
NOTE 1 When an ESPE includes a safety-related data interface, the response time is defined at the output of the
safety-related data interface.
NOTE 2 When a safety-related communication interface is included in the ESPE enclosure, then the response
time is defined at the output of the safety-related communication interface. In this case, the response time is also
dependent on the protocol and architecture of the communication network.
NOTE 3 If an ESPE has both a safety-related data interface and OSSDs, the ESPE can have a different response
time for the safety-related data interface and for the OSSDs.
Add, on page 21,after definition 3.28, the following new definitions:
3.29
safety-related data interface
direct connection (peer-to-peer) interface between the output of the ESPE and the safety-
related communication interface that is used to represent the status of the OSSD(s)
NOTE 1 A data interface will not have addressing capability.
NOTE 2 The safety-related data interface can be bi-directional.
– 4 – 61496-1 Amend. 1 © IEC:2007
3.30
safety-related communication interface
safety-related connection to a standardized communication network intended for safety-
related control functions
Page 23
4 Functional, design and environmental requirements
4.1.3 Types of ESPE
Add, at the end of this subclause, the following last sentence:
When a single safety-related data interface is used to perform the functions of the OSSD(s),
then the data interface and associated safety-related communication interface shall meet the
requirements of 4.2.4.4. In this case, a single safety-related data interface
