This European Standard supersedes EN 61175:1993. It includes the following sig
16、nificant technical changes with respect to EN 61175:1993: The structure of the signal designation has been extended and specified in more detail: the term “item designation” has been replaced by “reference designation” with the same meaning as before; the term “basic signal name” has been extended.
17、It has been replaced by “signal name”; then subsequently consisting of “class”, “short name” and “basic signal name”, where “basic signal name” has the same meaning as before;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
18、of signal and hence the “signal direction” can be recognized by the code; the concept of “signal name domain” has been introduced for improved identification of signal name in relation to an applicable object; the term “version identifier” has been changed to “variant” with the same meaning as befor
19、e; the earlier possibility to provide additional information on “signal level” has been generalized to an area of “additional information” to be used to supplement information on “version”, “time stamp”, “level” and other system related parameters. The additional information is stated to belong to a
20、 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 implemented at national level by publication of an identical national standard or by endorsement (dop) 2006-08-01 latest date by which the national standards confl

34、 and furthermore to make recommendations on useful presentations of these. Basically, a signal designation is associated to the signal over its whole lifetime, which means: from the beginning of the design stage until the signal is no more needed. Designation of a signal, in accordance with this sta
35、ndard, means that the source and the destination of the signal are identified, also in intermediate interfaces where the signal is delivered from one system/media to another, but the identification itself is independent of the media used for transfer of the signal. To comply with rules and procedure
36、s 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 systems as “additional information” if needed. The change of medium for the transfer of a signal because of a physical rebuilding of an installatio
37、n 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 influence on the identification of it, unless this physical transportation is a part of the signal purpose. Rebuilding of installations might lead to wi
38、shes 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 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
39、 this standard will be read as “signals” more than “connections”.

40、ernational 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 industrial system, installation and equipmen

The standard does not establish rules for the graphical/physical representation of a signal on devices, nor the graphical representation of signals in documentation. 2 Normative referenc
