Hi there,
I have used ACADE for several years and mostly the IEC2 symbol library.
I got a question today where I was asked to which IEC standard the IEC symbol library refers to.
I though that the symbol library was referring to IEC 81346-2 but when inserting a pilot light ACADE tags the symbol with the letter "H" (see attached image). However, according to IEC 81346-2 the component should be tagged with the letter "P" (Presenting information for purposes such as alarming, informing, indicating)
I hope that someone out there or preferrebly at Autodesk can comment on this.
Regards, Gary

Hi Gary,
According to Autodesk literature its:
IEC-60617
See the Following link: (until Autodesk moves it... 🙂 )
2 is the Text size (2mm) I think there was an IEC4 as well (with 4mm Text).

Hello James,
I´m aware that the difference between IEC2 and IEC4 is the different attribute size. The symbols are I think the same but the attribute sizes differ for instanse the TAG attribute is 2,5 in the IEC2 but is 3,5 in IEC4.
The IEC60617 library is based on 2 character tagging of components for instance a signallamp is tagged -EAxxx and seems to follow the IEC81346-2 way of tagging when detailed classification of an object is used.
So that´s why I´m asking to which standard IEC2/IEC4 refers to ?? If it´s IEC 81346-2 the tag for a signallamp (LED) should be -P and not -H right?
I have attached two images showing a section of the IEC 81346-2 for your information. The first image shows how a signal lamp is tagged with one characer i.e. -P. The second imaged shows how a signal lamp is tagged with two characters i.e. -EA
Thank´s again for commenting on this tread.

Hi Gary,
Ok so I did some digging, and found that the old IEC2/IEC4 is based on IEC-61346-2.
Which also has the Lights as -p... so I guess it was a typo?
In 2015 they went to IEC 60617 and it shows the -EA.

Correction:
IEC 60617 was added in ACADE 2012.
Hi Dough and thank´s for commenting on this thread.
I was aware of that using the wd_fam.dat file has this limitation.
Few other examples is that some of our customers prefer that timers are tagged -T instead of -K. Also motorstarters are in general tagged -K and not -Q so there´s alway´s some special requirements we need to cope with.
My intention with this thread is to get some input on what standard the original IEC2/4 symbols are based on (IEC 81346-2).
And finally what IEC standard will rule in the coming years IEC81346-2 or IEC 60617 ?

Allright, so the IEC 60617 library is based on the IEC 81346-2 and the tag letter coding for the symbols is based on standar letter codes of subclasses related to main classes (2 letter coding). The correct letter coding of a control relay would be -K using the main class coding but -KF using the main and subclass coding according to IEC 81346-2. It would be nice if Autodesk would update the IEC2/4 libraries such that they followed the IEC 81346-2 with the main class coding (single character) such that both libraries were up to latest standards don´t you agree?
Thank´s again and regards, Gary
