16、il: the term “item designation” has been replaced by “reference designation” with the same meaning as before; the term “basic signal name” has been extended. It has been replaced by “signal name”; then subsequently consisting of “class”, “short name” and “basic signal name”, where “basic signal name
17、” has the same meaning as before; classification codes have been introduced in order to facilitate the understanding of the signal name, for example the type of signal and hence the “signal direction” can be recognized by the code; the concept of “signal name domain” has been introduced for improved
18、 identification of signal name in relation to an applicable object; the term “version identifier” has been changed to “variant” with the same meaning as before; the earlier possibility to provide additional information on “signal level” has been generalized to an area of “additional information” to
19、be used to supplement information on “version”, “time stamp”, “level” and other system related parameters. The additional information is stated to belong to a variant of the signal (not to the signal designation in general). The following dates were fixed: latest date by which the EN has to be imple

32、 .45 5 EN 61175:2005 INTRODUCTION The intention of this International Standard is to make rules and requirements for the designation of signals, and furthermore to make recommendations on useful presentations of these. Basically, a signal designation is associated to the signal over its whole lifeti
33、me, which means: from the beginning of the design stage until the signal is no more needed. Designation of a signal, in accordance with this standard, means that the source and the destination of the signal are identified, also in intermediate interfaces where the signal is delivered from one system
34、/media to another, but the identification itself is independent of the media used for transfer of the signal. To comply with rules and procedures for different systems and media transferring signals, it is described in this standard how to handle special information in a system and/or in between sys
35、tems as “additional information” if needed. The change of medium for the transfer of a signal because of a physical rebuilding of an installation will not cause a change of the identification of this signal if its meaning is maintained. The kind of physical transportation of a signal has no influenc
36、e on the identification of it, unless this physical transportation is a part of the signal purpose. Rebuilding of installations might lead to wishes to transfer more signals in the same physical medium. All of such additional signals will be identified in accordance with their purpose and the rules
37、stated in this standard. As the identification of a signal has nothing to do with the physical transportation of it, the lines in the figures in this standard will be read as “signals” more than “connections”.

38、SIGNATION OF SIGNALS 1 Scope This International Standard provides rules for the composition of designations and names for the identification of signals and signal connections. This includes the designation of power supply circuits. The standard is applicable to all types of signals within an industr
39、ial system, installation and equipment. The standard is not applicable for the identification of wiring, terminals and other hardware for connections. The standard does not establish rules for the graphical/physical representation of a signal on devices, nor the graphical representation of signals i

45、ion network in the form of telegrams. Such messages may represent one or several signals. 3.2 signal designation unambiguous identifier of a signal within a system 3.3 signal connection path on which the signal is transferred between the interface points NOTE The connection can be identified as logi
46、cal or physical, and can be realized in different connection media. A complete signal connection chain may include different media. 3.4 signal connection chain group of coherent signal connections belonging to the same signal NOTE The signal connection chain will typically describe the complete conn
47、ection of the signal transfer. 3.5 signal connection medium medium in which the signal is transferred from one point to an other NOTE The medium can be identified as logical or physical, and a complete signal connection chain may include different media. Examples: - Physical media: electric wire, op
48、tic fibre. - Logical media: single data transfer, communication bus or network. 3.6 signal name domain chosen object in which each signal name is unambiguous without using the reference designation 3.7 signal presentation way of presentation of a reporting signal NOTE 1 Example: digital display, ana
49、logue indication, lamp, semaphore. NOTE 2 The complete signal designation does not have to be used in the presentation (but it can be). It is recommended that the complete signal designation should be possible to find from the signal presentation. 3.8 signal kind super-type of the signal class defining direction of information in the signal connection NOTE Two signal kinds are used: - reporting signals; and - controlling sign
