Is it part of the IEC spec?  What I see is that ENUM is a user defined datatype, which is already available.

What specific example or problem are you trying to solve?  Screenshots welcome.

Hi

When is the data type ENUM scheduled to support the S7-12xx and S7-15xx PLC's? When you are used to SIMOTION this is really needed in the PLC's

I do not work for Siemens, so quoting specs and such has no effect on me.

I will however repeat myself.

What problem are you trying to solve where ENUM as a system data type would make it easier?

 Enumerator is not only a user defined datatype, An enumeration is a complete, ordered listing of all the items in a collection https://en.wikipedia.org/wiki/Enumeration. Almost all languages consider Enums  https://en.wikipedia.org/wiki/Enumerated_type  , but not STEP7! 

And it seems to be part of IEC 61131-3 https://en.wikipedia.org/wiki/IEC_61131-3

Did you not read your own Wikipedia link?

From IEC_61131-3 on your provided Wikipedia link

Data types
...User-defined Data Types Enumerated data type
      Enumerated data type with named value
      Subrange data type – puts limits on value i.e., INT(4 .. 20) for current

For purely theoretical or academic unhappiness, see the attached image on where those types of comments / complaints are best directed.  Wasting them on your fellow Siemens end users is of no use.

I repeat myself:

I can help or offer suggestions on how to solve real-world PLC related problems using TIA portal as the tool for accomplishing some task.

I cannot help you fulfill the need to complain about the weather to a fellow tree who does not like the way the wind blows. 

I did suggest you speak to the right resource where they can change the direction the wind blows.

 If I say you that spagetti are food, do you think that any kind of food can be called "Spaghetti"?

"Enumerated data type with named value" Step7 have not named value! It has only variable and constants, not named value.
